Yeh, I'm sure there's already a topic like this up on the forums, but I've owned Street Fighter IV for two days now and am officially hooked.  That having been said, who is YOUR favorite character to use and why?
Personally, I enjoy using Fei Long.  I used him a lot back in the day when I played "The New Challengers on my Genesis", and like him here, too.  All the "experts" say he's low tier, but I've been having some moderate success (and great fun) with him fighting online.  His out of control fighting style fits right in with my spastic thumb movements.  My strategy: 1.) Beat guy into corner with Rekka Ken 2.) Keep hitting him with Rekka Ken until he gets knocked 3.) Profit
Besides, Bruce Lee look-alike = Win.
What about the Giant Bomb community?  Who do y'all use?

I've always been boss with Chun Li.

I don't have 4 but on SFII: The New Challengers on Genesis and more recently on HD Remix I've been playing as Cammy a majority of the time.  I also play as Sagat once in a while.  I agree about Fei Long, do that one move repeatedly and you can't lose.  Cammy's Thrust Kick/ Cannon Spike (I've seen it called both, which is it?) works in a similar fashion.

I'm best with Zangief, but starting to get good with Honda, and going to try Chun-Li soon. Then there's Ryu, who everyone's good with.

Sakura and Cammy.

Right now, in order:

Sagat is my main, followed by Ryu, then Abel.

"PureRok said:

"Sakura and Cammy."

This."

My top four are: C.Viper, Chun-Li, Sakura, and Ken.

I guess I better actually post my "rotation" rather than just my fav.
Fei Long, Abel, Sakura, and Gen are who I'm currently using.

I use Abel.

Sakura, C.Viper, and Cammy... wish Guy was in IV

C.Viper, Rose and Cammy.

El Fuerte
Dan
Balrog

In that order.

I'm loving Gouken right now.  Not only do I not run into him too often online, but as an old Ryu player from SFII days, he suits my playstyle perfectly and has a few additional tricks up his sleeve.

The character I hate fighting against the most is Cammy.  Her kicks come out so fast it's hard to counter them.

The characters of Sagat and Balrog (Boxer) concept wise have been Hulk's favorites for years.   Hulk played a lot of Zangief and Honda in HD Remix so they've climbed the list as well.  So far in SF4  Gouken is getting a lot of Hulk love along with Dan for his surprisingly effective Ultra.  Also planning on putting some time in on Abel and getting solid with him.

I've been using Chun Li as my main. I also like C.Viper, I'll probably practice her more next. Also love playing with Akuma and Fei Long. Oh yeah also Ryu and Ken... because of the SF and SF2 days.

Man, now on about my second week of play, I'm still not CERTAIN who I like.  Initially I was staying away from charge characters, but now I've begun using Guile and Vega and really like 'em.

I like Dan.

Now, I started playing Dan because it throws the opponent off and it's fun to jump + taunt over fireballs. Oh, and because if I lost, I wouldn't feel as bad because I'm Dan. Then something horrible happened. I actually got pretty good with Dan, and he's my go-to guy, even in arcade mode.

Now I don't have an excuse when I lose, and that kind of sucks.

Ryu.

I love playing as E Honda, but I'm getting over the idea that I will ever be any good at street fighter. Almost ready to give up on network battles all together.

The last guy I was really good with (and the in last SF game I played) was Adon.

Now, Abel looks cool, but I'm more of a Virtua Fighter guy now.

While I didn't play much SF2 until way after it came out, but I did sink an ungodly amount of hours into Street Fighter EX plus Alpha and always gravitated towards Akuma. Even when I got into SF2, I almost always went with Akuma there too.

Gotta respect a character whose introduction to the series is to kill Bison with one move.

1. Dan
2. Ken
3. Random

Ryu
Sagat
Guile
Balrog
Dan

I'm going to try Gouken once I get him.

right now mine is sakura, when i get better with her, i will look for my secondary

Ken, then Ryu, Dan, Sagat, and Fei Long

I'm all about Sakura. Fast, shoto-ish and easy to play with the shitty Xbox 360 pad. Though I do use Fei Long sometimes. Thinking about switching my main to Chun Li when my stick arrives. Now it's just too hard to be in 100% control over her.

Probably Blanka.  After playing for about 2 weeks online, I didn't see anyone using him, so I picked him up.  I played about 25 Player Matches today, and won about 20, after winning 5 of my previous 35 matches with other characters..  Most people are weak against him, since they don't see him much..
