Breathless right? LOL. Folks here are toooo funny. Few months after super came out I said it was 6-4 Abel once he got U2 loaded. Doods strait ripped me a new one. Timed passed, talked with pro players offline, watched the streams and a year later it became clear that if the Gief knew what the hell he was doing, using U2 would be just as much of a guess for you as it is him. I dare you to use U2 vs a top tier Gief. Sure he cant just press buttons with long delay, but so what. s.mp FTW anyway.
If your playing footsies with Gief, you are almost guaranteed to hit at least 1 step kick, which means step kick combo, which means U1.
As far as what the MU odds is now, this will probably be debated till the end of the series. Alot of Gief mains feel its even, Abel players still feel disadvantaged shrug.
