Who is your favourite team mate in Mass Effect 1 or 2? 
 
I always take Garrus, as he's been by my side through both games. But I also love the quiet badass Thane, as you can probably tell from my Avatar.

Garrus all the way. Every one is pretty good though. except for Jacob. F that guy.

Grunt is always in my team purely because he's a tank and hardly ever gets taken down when you bump his fortification up. He can also wield the assault rifle and shotgun so he's useful in most situations. I usually go with Garrus along side cause I love his quips and packs the sniper rifle.

First game, probably Wrex or Liara, and in the second game Thane and Miranda.

 ME1: Adept-Shepard + Liara + Tali/Garrus - double Singularity and Stasis in addition to Overload, Hack, Sabotage
ME2: Adept-Shepard + Legion + Miranda - Hate using Miranda but she adds HP and Attack damage to the whole squad, also has Overload/Warp, Legion brings Hack, Combat Drone and Infinite Widow rounds - can deal with just about any situation given the powers on hand.

miranda for the second one because SHE HAS NICE ASS and also cuz she has both kinetic and engineering skills. in the first game i just loved wrex cuz hes such a badass :P

Garrus. Especially with the female shepard romance added. That was so cute and hilarious.

Garrus and miranda for ME2. I banged Miranda ;)

"I banged Miranda ;) "

Easily Wrex

Mainly used   Garrus and Tali though the first and second game on my first play though, in two i found Grunts, Thane pretty awesome characters. 

grunt is by far my favorite. legion is a close second.
 
though i always use grunt and garrus, as they fit my play style perfectly.

Garrus by far. Thane and Legion are tied for second.

I usually play a soldier so I'll take Tali and whichever biotic I like.  In the first one it was Liara. 

I find Legion the most interesting, but always take Garrus and Miranda out to the parties.  In the first game it would usually depend on the playthrough but I would usually take Ashley and Kaidan.

When you got Legion his special sniper rifle and increased his damage output instead of increasing his health he became the most powerful companion in the game because his shots became one hit kills.

Wrex, obviously.
 
 

I rolled Wrex/Garrus in 1 and Garrus/Thane in 2.

" Easily Wrex "

Wrex/Garrus in ME1 (The other companions were meh).
 
Grunt/Subject Zero in ME2.
 
Krogan's are just bad ass and unstoppable, Garrus due to lack of interesting squaddies in ME1 and Jack is just a bad ass character, even if her combat skills are mediocre.

Easily Wrex, followed by Garrus.

Everyone except for Jack and Ashley...they were awful. Kaiden and Jacob were meh.

Wrex and Kaiden for ME 
Thane and Tali for ME2

In ME 1 definately Tali,so useful for scavaging and geth are never a worry with her around

Wrex and Thane

Wrex or Garrus. 

I've only played ME1, but Garrus is my favorite, by far. I'm playing the "new game+" with Garrus and Liara as a Vanguard.

ME1: Liara & Kaidan  (though Kaidan's such a puss.. Liara did the "make sure he's dead"-thing when I brought the duo to the end fight)
ME2: Miranda & Mordin

ME 1: Ashley & Wrex, pretty much all the way through the game (I didn't get the Krogan Ally achievement, oddly enough). My Sentinel defintely needed the tank support and firepower, since I really didn't know what I was doing for the first few hours
 
ME 2: Miranda plus either Thane or Garrus, playing as a Soldier.

Pretty much used Wrex and Tali during ME1. (Wrex survived even, so fudge yo' couch Ashley), pretty much because I met them early on in the game and wanted the achievments. Should be noted that Ashley died as well.
 
During ME2 however, I usually mix up my team a bit, but I think of Jacob and Miranda as a good combination, especially if you go as a soldier, you provide long range, they do the rest.

Either Wrex or Garrus.

Thane was pretty sweet

Jenkins.  Never Forget.

It's got to be Garrus for me (not surprising considering my avatar :P), although Tali would be a pretty close second. She's just so adorable! The series has such a strong cast of characters though, I actually feel bad for choosing. The only character that I never really cared about much Ashley, Kaidan and Zaeed, but even they I can't say I actually dislike. Well, maybe Zaeed. Yeah, that guy can go to hell.

really depended on what i was doing. But on ME1 once i had Wrex it was Wrex all the time!! Loved him and Garrus or Tali. 
 
ME2 was between, Miranda, Jack, Tali and Garrus, but i can say that i used all of them but the Geth or Samara i really hated those two characters. 

Miranda, every time. Warp and Overload make her useful in every scenario, and the passive buffs are very nice to have. Playing as a vanguard, teammates are only there for their abilities and passive buffs, occasionally they freeze something with squad cryo ammo while I kill everything.

Garrus in both games, hes my go to guy, hes got my back! ^_^

In Mass Effect 1 i always had Liara and Ashley and in ME2 i usally brought Miranda and Samara. Overall i feel the second game has more memorable characters.

Jack by a long long way.

ME1 Wrex & Tali

ME2 Tali & Garrus/Miranda

In terms of who I want to bring to survive Insanity:
ME1: Liara and Ashley. Spamming Liara's biotic stuff and Ashley to provide additional levels of beefcake.
ME2: Miranda and Mordin. Mordin's Heavy Incinerate and Miranda's Heavy Warp and Heavy Overload make those near impossible fights way more bearable.
 
In terms of who I think is awesome as a character:
ME1: Wrex, Garrus. Wrex for being a complete bad-ass constantly, and Garrus for some pretty nuanced character progression when it comes to arresting/killing a criminal.
ME2: Wrex, Jack, Mordin. Wrex, still being a bad-ass, Jack for her character development and Mordin for being hilarious and quirky.

ME1: Wrex 
 
M2: Grunt and Legion

In the original game it depends entirely on your own character to see who compliments your class best. In Mass Effect 2, it's Miranda. She's the best all-around party member by far. Having Warp and Overload gives her versatility to help with all types of enemies and her Cerberus Leader class ability makes the party as a whole do more damage and have more health.

I like the Wrex/Grunt and Garrus combination.
Has anyone noticed that in ME 1 that all the women are pure classes (100% biotic etc)   
 
And they say men can't multi-task! ;P

Garrus, Mordin, Tali, Miranda, Wrex... who am I kidding? They're all great!
