Good Ol' mutey. He didn't have to say anything. He just kept his mouth shut like a good package boy.

Niko.

Niko was the only one with an interesting backstory.

Nico. Mainly for his funny accent and good backstory.

I have to agree with these people. Unlike the other guys who simply took it upon themself to thrust into a life full of crime and murder, Niko was forced to go to Liberty City, forced to steal, kill and lead a life of crime, it simply wasn't his fault.

Toni form Liberty City stories. Niko was quite cool but I never understood all the love for Tommy.
The list in order would probably be:
1. Toni
2. Niko
3. Vic
4. CJ and Tommy tied
6. Claude

CJ for me. Just because that game is so absurd. Also, since I have yet to play GTAIV.... sadly.

I didn't really like the games but, I do like Brucie. He's an odd character.

Tommy, he's got a lot more personality than Niko, plus Niko always whines about killing people' how he is forced to do it but hates it and his trouble past, blah blah blah. Generally when I am controlling him he is all about the mindless violence, it just doesn't work.
Whereas Tommy knew he was into a GTA games and was well up for driving along the miles of pedestrian walkways sending old ladies flying while drive by-ing helicopters. The man's a legend.

Tommy, for me. I liked Niko, but not as much as I liked Tommy, and I didn't empathise with CJ at all.

Tommy Vercetti is voiced by Ray Liotta there for, he is the best one.

Vice City also has Dennis Hopper and Burt Reynolds doing voice.

tommy was cool , cj was too getto gang banger and niko was a bit to foreign but then there's claude he kept his mouth shut and just did his job all other characters in the gta series don't matter as for lost and dammed i haven't played it yet

i like Claude! i mean he had no personality at all and he was just a labrador really, but his story was the best. then tommy vercetti because he was just bad ass.
the rest have just been to boring for me to give a shit about...

Tommy was easily the best. Then joint between Claude and CJ (all about the customization). Frankly Niko just annoyed me, and was one of the main factors that lead me to dislike the game.

Tommy all the way. Ahh, I remember being in a mission hosing down a mall with minigun fire while Ray freakin' Liotta yells "I'm Tommy Vercetti, remember the name! I run this town! ME!". What a legend.

I was personally rooting for Sam Jackson in GTA IV.

Second.Third.Fourth and Fifth that emotion.

Niko Bellic.

easily Tom

(he reminds me of Dexter)

Tommy or CJ I can't choose x.x
Tommy was awesome.
CJ Was funny.
....CJ.
"What does it look like I'm made of puddin!?"

"CJ" Carl Johnson

I was saying "Yo, Sup Ceejaay" for ages after playing, and speaking all ghetto with my homedawgs when cruisin for bitches.

But I prefer Tommy. I liked his shirt.

Niko's the only protagonist i gave a flying fuck about.

Johnny

Niko. Interesting backstory and good lines (and accent) made for a very memorable character.

Johnny Klebitz, 'cause he's a hardrocking biker that drives around on his awesome chopper and kicks people in the face.

Niko Bellic, because he said this:

"Nobody fucks with my family!"
