Since theres seems to be a wide range of opinions regarding which characters people love and hate, I pose this question to the masses to settle the 'debate'.

Who are your favourite and most hated characters in Persona 4?

My fave was definitley Rise because that girl was just caraaaaazy, whilst my most hated would hands down have to be ol Mitsou Kubo - that kid honestly scared the bejesus out of me everytime he was on screen.

Man, I hated Mitsuo so much.

Mitsuo and Teddie... Mitsuo is just some crazed idiot, and Teddie... he is sooo annoying..

Faves:

Loved:

Gotta be Mitsuo. I remember seeing him at the beginning of the game and being freaked out at his eyes.

THEN, I remember playing the game at 4AM, and having his face pop up on the screen. Jesus christ. He and Izanami chilled me to the bone.

Loved:
Yukiko - I could kind of relate to her character progression. At least to the whole "breaking out of the shell" aspect. My most favorite character of the game.
Chie - There was never a dull moment with her. Second favorite character.
Yosuke - Knew how to get under peoples' skin which created some interesting and memorable moments in the game.
Rise - Like Chie, never a dull moment.
Kanji - I felt he was the only character that was capable of getting straight to the point of the matter.
Naoto - She was very key in solving the case. Perhaps I would of liked her more if I was able to do the social link with her.
Nanako - The youngest mature character I have ever come acrossed in a video game.
Dojima - A very awkward father figure but he always meant well.
Teddie - He was a hit or miss for me but I never outright hated him. Annoying is a better fit (at least when he was in human form).
Funky Student - He blew my mind with his riddles.
Mysterious Fox - Leaves.

Hated:
King Moron - The design of this character is obviously meant for us to hate him from the start.
Mitsuo - Scumbag.
Adachi - Scumbag on a higher degree.
Saki Konishi - No, I don't think she deserved to die, I just hate two faced people.
Hanako - The most delusional character of the game.
Noriko - Who let that cougar out of her cage?
Izanami - Chie said it the best, "Stop assuming you know us!"
2 Girls working at Junes - DO YOUR JOB YOU LAZY BITCHES!!!

Kanji was always my favourite character. Weirdly relateable.

Naoto got on my nerves, but I can't say there was a character I really hated.

Favourites:
Dojima - because he's a kind've badass detective and a good father figure all at the same time, despite his flaws
Yukiko - because she's feminine and intelligent and badass.  One of the best female characters I've ever seen in a game.  Her badassness is nice and subtle and not overbearing
Rise - for many of the same reasons why I like Yukiko.  I often don't like super girly characters, but she had a lot of unexpected depth
Kou and Daisuke - Their social link stuff was really fun, even though I never finished the link, I wish I could have because they were cool.  I restarted the game after going through about 20 hours and went with soccer instead of basketball like I did the first time, and basketball was more interesting, but I still like both of these characters a lot.
Nanako - I was kind've ambivalent about her at first, but once she went into the hospital and I came home to an empty house every evening, I realized how much I missed her saying hello to me every day.

Disliked and/or found annoying:
Chie - I tend to not like OMG DEFENDER OF JUSTICE characters, I like them to be a little more grey area than she is
The drama club girl - oh god, cry more please
Teddie - he mainly annoyed me.  I hated the sound of his footsteps whenever I took him out, which was a lot, because he became part of my final party.  He had his moments, but overall I wound up not liking him all that much.

Characters that I was torn about:
Yosuke - I liked Yosuke and I didn't.  He is the Persona 4 equivalent of Junpei in Persona 3 (at least characterwise -- in battle he's more like Akihiko), but a lot less foppish.  I kind've missed the fop aspects.  Also really disliked the way they made him rag on Kanji's sexuality all the time for awhile there.
Kanji - Sometimes I loved Kanji and sometimes I didn't.  I really disliked the way they handled his sexuality and it made him a little bit creepy.  I would've prefered that they either made him gay or took out the sexuality stuff, all of Yosuke's weirdness about the whole thing made me a bit uncomfortable.  But then, it is a Japanese game, so I can kind've understand why they handled it the way they did.  Also, I almost never fought with him, he totally didn't suit my play style.
Naoto - I think I would have liked Naoto a lot better had I been able to finish the social link, but I wasn't and she just seemed really incomplete to me.

Favourites:
Rise - Too cute, especially when she squeels, also her drunken PERONNNA scream. Her christmas eve text message was great too.
Yukiko - Started off quite dull but was good to see her loosen up over the storyline (KINGS GAME), turned me around.
Kanji - Says what he thinks and its usually funny.
Teddie - Bear only, very funny (Shoo bee doo bee).
Adachi - He was a good character until the end and then he got better.
Chie - Think Jeff can explain this one.
Female Student  - On the first floor by the lockers, she was always so nice, I wanted a social link with her!

Disliked:
Naoto - Never really loosens up in the group scenes, lose the hat.
Nanako - Yes, someone told me when I was halfway through the game that she was the killer, so I spent 40hours trying to work out how it was possible, drove me nuts.
Yumi - Sorry, too much drama for me.
Hanako - Her sitting in Soujis seat at the end was just creepy.
Teddie - As a human I found him annoying, only seemed to be hitting on the(my) girls.
Ai - For how she treated Rise when they clashed in Okina.

"Adachi, another character gone mad without enough good motivation.  They should explore the crazy characters more.  Whether it be with compassion or something like a horror movie.  Just add some depth, make them more than 'an evil bastard'."

Loved:
Rise for her social link storyline and just for being a fun character
Yukiko for being a pretty complex character
Yosuke because it's difficult to dislike him and still like the game.  He's basically the main character.
Nanako because she's just so darned cute.
Teddie because...well who doesn't love Teddie?

Hated:
The slutty teacher and Hanako
King Moron
Mitsuo.  Oh God, his eyes!
The rude ass press covering the Amagi Inn and pestering Yukiko.  They need to burn.
Kanji.  He annoyed me to no end.
Naoto just seemed bland.

*POSSIBLE SPOILERS MAYBE?*
Loved
Chie: "GALACTIC PUNT!".  Says it all, really.
Yukiko: I related to her on a personal level because of the whole Amagi Inn sub-plot (though I'm inheriting an apartment building rather than an inn).
Yosuke: He's a great all around character, as well as the best acted character.
Teddie: Though he's a little annoying at first and some of his Social Link stuff kind of sucks, he's hilarious!
Nanako: Welcome home, big bro!
Dojima: Though kind of boring in the main story, Dojima has a fantastic sub-plot.
Naoto: Because her Christmas Eve scene was adorable.
Adachi: I was definately surprised to find out he was the murderer, and he had some interesting things to say...he's a good villain.  Also, he loves cabbage.
Kanji: Great character.
Rise: I hated her at first, but she grew on me.  She sucks during battles though.
Margret: An intersesting character, particularly once you finish her S.Link.
Kou: He loves them balls.  Plus, his Social Link ended up being really cool.

Hated
Pretty much everyone in town: I have absolutely no motivation for needing this, but can you find me some hard boots?  If you could that would be great.  I think you could find it someplace HOT AND HUMID.  Why won't I find it?  Well, clearly I'm too busy blankly staring into space to do it myself.  I HATED the townspeople.
Mysterious Fox: Everything he gives you is an annoying, painstakingly slow side quest, and you only get a discount out of helping him.  Why does he need to charge you in the first place?!  I'm saving the ****ing world, fox!  I don't HAVE 30,000 yen!!!
Sayoko (the nurse): Annoying.  She's just...agh!  The whole "WHY DOES EVERYONE LEAVE ME?!?!" thing just made me want to punch her.
The young mother: The worst mother in the world.  Ever.
Ai: She just sucks.  That's all there is to it.
Yumi: Just like Sayoko, I got really, REALLY annoyed at her character.  So damned self-absorbed.
Ayane: She also just kind of sucks.  Though to a lesser extent than Ai.
Daisuke: Kind of pathetic, and his story was WAY too cheesy for me.
The stray cat: I DON'T WANT TO FEED THAT STUPID CAT ANYMORE.  WHY DO I FEEL COMPELLED TO?!
Nice Guy and Tough Guy: Remember these guys from the Kanji boss fight?  I don't know why but they annoyed me beyond belief.
Naoto's Tie: I don't know why exactly, but something about that tie just rubs me the wrong way...

Loved:
Yukiko - She's really awesome as well
Kanji - Pretty cool guy.
Rise - Really funny character, imo.
Chie - Silly all around
Nanako-chan - Love her, she's just too adorable.
Naoto - Christmas Eve... awesome.
Dojima - Awesome father/detective.
Adachi - Good villain in my opinion. The things he said before the fight was pretty awesome.
Kou and Daisuke - Pretty chill guys to hang around with.

Neutral:
Teddie - Got on my nerves quite a bit, but he was funny at times. Although, I did love his ending speech on the true ending(or was it on the normal ending as well?)

Hated:
Mitsuo - Can someone just shut this idiot up before the boss fight?
King Moron - I was honestly glad that he died. He fit the "too stupid to live" role.
Yosuke - The way he kept reacting to Kanji got on my nerves. Obviously he didn't comprehend what Kanji was really feeling. That, and his asshole moments got a tad annoying.
Hanako - -_-

Adachi's cabbage loving ass was fantastic, His Izanagi was pretty bad-ass too.

He's so awesome we made an Adachi appreciation forum over at Creepypasta.com's forum

Other than that, how could you not love Chie. I'm on my second playthrough and it kinda feels dirty that I'm gonna have to try to hook up with one of the other girl's too see something new.
Then again, I could always go for the sausage party.
I also have a mancrush on Kanji.

I really didn't like Sayako's turn in the S.link about halfway through. At first it was fun, but then she got all melodramatic and somber.
Yuki was a self-absorbed bitch. I wanted to quit her. Especially now on my second playthrough when I keep trying to boost Ayane's confidence. She's so sweet ^_^

" I keep trying to boost Ayane's confidence. She's so sweet ^_^ "

Every one I absolutely loved except Mitsuo and Moraoka.

Like:
Margaret-I like her dress,voice and she is beautiful.I hope I could have girlfriend like her:P
Mysterious fox-Its social link help a lot for battle because I can level up quickly by getting Haikara shirt and Musashi shinai by trading with Guardian fish.Guardian fish can only be caught when Fox social link is Rank 9.
Tutored student-Only 1 reason I love this character.His social link(Tower) help me fusing Yoshitsune,the most bad ass persona.

Dislike:
Hanako-Ugly!Fatty!And so on...
Mitsuo-What an irritating psycho!
Rise-She speaks too much in the battle,forcing me to turn the voice off.
Yumi-Very annoying especially in the hospital.

                           

Like: I loved Nanako because she was just sweet, I also liked king Moron cos I found him to be hilarious (if really pervy), also funky student and mysterious fox ftw!!!
Dislike: Teddie- I just found him to be really annoying. His voice really got to me and I really don't know why.

My favourites are Nanako, Dojima and Kanji.

Liked: Nanako, Mitsuo and Adachi (even at the end)
Disliked: Kinshiro Morooka

"Yosuke - I liked Yosuke and I didn't.  He is the Persona 4 equivalent of Junpei in Persona 3 (at least characterwise -- in battle he's more like Akihiko), but a lot less foppish.."

Yosuke couldn't hold Junpei's jock.  L)  (Junpei Iori in my opinion was the best character in P3 and P4 combined, although I thought the cast was stronger in 4 overall.  By far the deepest and most conflicted character in S.E.E.S.)"

I didn't dislike any of the characters except for Mitsuo, who was just pathetic and out of touch with reality, and Yosuke, just because I know people like him in real life who I dislike and he's always being an ass towards Kanji.

"Liked: Nanako, Mitsuo and Adachi (even at the end) Disliked: Kinshiro Morooka "

Well I didn't have any problem with any of the characters aside from Kashiwagi and Hanako.

Kashiwagi was just creepy.

And Hanoko doesn't  need any explaining.

" DANGEROUSLY SUPER SPOILERY AHEAD!

Whew! For a second I thought I was the only one who liked Mitsuo as a character. I mean...a teen who was so creepy he was ignored, so lonely he tried to escape reality by playing games at the arcade...in the end he, much like a young child, wanted attention, and any kind was good enough for him. He saw his chance and he jumped at it.That's my interpretation of him anyway. It explains the baby/fetus thing- he was socially and emotionally stunted. I have to wonder what his home life was like...if he lived in a normal household or not. I don't think his parents were abusive. On the contrary, I think they were kind but not really around as much as they could have been, or let the TV watch him since he was born. Eh, maybe I'm just overthinking him since he really wasn't explained very explicitly. It was more subtle.Anyways...I liked pretty much every character except for Mrs. Kashiwagi and Hanako. Not really crazy about Ai though, nor Eri. "

That's also pretty much how I saw Mitsuo and I felt sumpathy towards him.  What would have been great is if you could have established a social link with him afterwards to have a better understanding of him, but that didn't happen.  He just wanted to be in the spotlight for once and not be ignored/alone all the time.  But as his shadow represented him, a baby, he is immature and is acting like a baby since he wants all the attention.

Late reply is late.  Junpei isn't my favourite P3/P4 character (Akihiko and Shinji are my favourites), but I do like him a lot better than Yosuke.  While Junpei is far more complex characterwise, they do both play that role of conflicted best friend to the protagonist.  Although Junpei really does have a lot more going on and is far more important to the story of P3 than Yosuke is to the story of P4.  Really, I like P3's main characters better than those in P4 all around.  They all have more interesting problems -- although they're all a lot more messed up than your typical group of teenagers."

Late reply is cool.  :)
I don't mind that he gave the MC grief nearly as much as I want to bitchslap Yosuke sometimes when he's in conversation with Kanji.  "

I have nothing but love for all those characters.  I even liked hating Mitsuo, Morooka, Hanako, etc.  I suppose if I had to pick favorites, I'd go with Chie, Dojima, Nanako, and Naoto, but really, I couldn't ask for a better cast of characters.  Persona 4 had a sentimental do-rama feel to it, for sure, but despite cartoonish flourishes of aidoru, child detectives, and a talking teddy bear, I don't think I've met a more relatable, charming, and simply honest group of video game characters.  They had less conspicuous baggage than the cast of Persona 3, but I thought that ultimately made their problems  a lot more human and genuinely teenage than 3's thematic pretensions.
