in the arcade version when you do ryu's shinku haduken super you don't slowly fall down to the ground.

in mvc chun li is in the game while sentinel is a helper ( a secret one i think )

if you block maximum carnage in the game the super gets cancelled not like in this one.

in mvc ryu has shin shoryuken(sorry bout buthchering the word) in xmvsf both the arcade and this version he den't have it.

cyclops is missing his air optic blast super and the charge move of when he grabs his opponent.

this is all i can think of right now if i think of more i'll edit this post.
