The PS3 is definately more bang for the buck. Bluray player, built in wireless, free online gaming.
Xbox still has a better catalog, but the ps3’s has been growing.
I’m guessing after the last xbox ban wave, with people not being able to play backups online, they bought ps3’s. Cause if you’re going to play online you may as well do it for free (and keep their banned 360’s for backup play offline).
