Right now its hands down 360. Been out for over a year already(i.e all the bugs/problems have been fixed). PS3 is still VERY buggy, and is far behind in quality games. Probably be another year or so before the PS3 really gets going.
Edit: PS3 just costs too much right now. You're basically buying a Blu-Ray player because the PS3 doesnt offer much else right now. You can get a 360 and Wii for the same price as PS3.
