Should I buy a Xbox 360 or a PS3 ?

[sly777]

I already own a nintendo wii. The console is pretty great but I would like to play games like sport games (hockey, football and basket...), RPG, Shooters...

I plan to buy a new console but I don't know which one to choose ( of course). The two console seems pretty cools but I would choose a console that offers a lot of games. I don't care about movies, photos, music...

Should I buy a Xbox 360 or a ps3 ? Please, don't be fanatic... I don't want to start a war, I just want to find somes answers

Thanks !
