well price is very similar. XBox graphics and CPU kill the PS2's. XBox live > PS2.
PS2 has more games, but XBox has some exclusives as well. I modded my xbox and it's 20x better then a PS2 now. You don't need a review to tell you that the xbox is more powerful by a long ways, but the PS2 has been around longer, has a ton of more games, and you don't need a stupid DVD remote to play DVD movies.
