It's pretty much the same on both consoles, but the PS3 version doesn't have an install option. The load times are long, so go for the 360 version to curb that.
Also agree that the reviews were amazingly harsh on this game. The game has faults (load times, "cheap" platforming, etc), but it is better then the reviewers would like you to believe.
