My favs for each fighter i still play.
GGXXAC - Eddie. Best puppet based character ever made and it shows. And ya, i defiantly know how broken he is.
Mahvel Baybee(Mvc2 for most people) - Sentinel or Iron man. Its just that i like how he can set the pace to the match, and he can hit so hard if you just screw up a little. that + drones assist, unfly unblockable lasers, and HSF, = pwnt scrubs. And IM is just awesome. He's a bit clunky, but his assist controls a lot of space and his infinite is really easy to pull off.
BB - Noel. Great rushdown, crazy mixups into HUGE combos (6.5k combo on Tager?!?!), dodge dead angle, and very good air abare. But no combos after safe lows on standing characters is really fucking stupid. I should be able to do 2b, or 2c into an ok combo (2.5-3k), but w/e, she still knows how to get me my money

. Tager would be my second fav cause of all the resets and magnetism shenanigans. But no anti-airs that work right, and having 2 3/7 and 2 1/9 matches is fucking retarded. He works online and vs people that dont know how to play top tiers, but once someone knows what their doing shows up, your pretty much going to get skull fucked if you stick with tager.
3s - Urien. Unblockable Aegis reflector setups and chariot tackle loops are fucking dope... Need is say more? Also Yun + Geni-jin = me being sad he isn't in SSF4 T.T
SF4 - Abel. Great mix-up and rushdown. And he confuses the hell out of people that dont play him (which is 90% of people that play SF4) standing light is awesome for footies (stuffs shoto cr. mk) st mp beats all self propelled attacks (besides cannondrill cause its too low) But his bad matches are really fucking bad. like 2/8 to 3/7 bad. It just annoys the shit out of me when i lose just cause of match-up and not cause i had to fight a better player.
And last but not least...
SSF2T - Claw (vega/balrog). Cause im a dirty, shameless bastard. Easy links, great pokes, easy as hell tick throw set ups, off the wall shenanigans and more stupid shit that makes him awesome. Kinda bad on wake up, and he sucks ass v blanka but w/e.
I care more about function more then aesthetics, and I try to rushdown with whoever i play with.
