I would have to say the Xbox for a few reasons.
1. A much better controller. it is alot more comfy then the ps3 controller.
2. There are alot of great games on the xbox. it has a much bigger library then the ps3 and has some good exclusives.
3. The price. You can get an arcade bundle for about 120 quid which is fantastic value if your a light gamer. £160 for the works which is still cheap next to the ps3.
Also while the xbox has had some terrible problems with the red ring etc the new consoles have been rid of this problem and are alot more reliable.
