Well...

I'd say ps3. (no idea wich one)
Because: No red ring of death. Better quality. Doesn't get overheated after 10 minutes of gameplay. Free online accounts.

just to point this out, the ps3 has what's called "ylod" or yellow light of death. it's similar to what happens to the xbox.

However,

there are pros and cons to both systems so it really comes down to preference,

as for my personal preference, i would say the ps3 because even though the 360 has gears of war 2 and 3, halo 3, odst, fable 2 and other xbox only titles, the ps3 has more features that i like. i prefer the ps move over kinect, bluray, built in wireless, free online,and the controllers.
