Which Fighting Game should I get?

Marvel vs Capcom 3 100%

I have both Street Fighter IV and Super Street Fighter IV, Super Street is basically the better more updated version of Street Fighter IV

MVC3 is the newest fighting game out

I have MVC3 its really fun, so many crazy moves

Here is Akuma in MVC3

You can see how slow the game play is in SF and how MVC3 has more moves

MVC3 has 38 characters (36 in the game and you need to buy 2 from dlc)

SFIV has 24 characters
