ive had both, and i prefer my ps3. the xbox 360 has a lot more noteworthy games by far, ps3 to me is a far superior systems and is expected a have a lot of great games this year

also, the 360 makes a very annoying humming sound which drove me crazy and the ps3 is virtually silent

but to each his/her own.. they are both great and you will enjoy any of them, just be sure to get the various things needed for optimum hd gaming
