As I see it, the two are largely interchangeable. The real difference you need to decide on is which system has exclusive games you want and which one you think looks and feels better. Don't let fanboys convince you on all this other junk, its mostly minor things that nobody even cares about. Fanboys like to point out ever excruciatingly minor point that marks the difference in system and say how superior it is. Also, try using both systems (by asking a friend or going to a game store) before hand to experience them hands on.
