Now I have both... I've had 360 since it came out, and I just recently purchased my PS3, but I have been around it for a year or 2 since my cousin has had it. At this point, I feel PS3 is way better then 360 just for simple reasons such as: Online is free.. I shouldn't have to pay to use MY OWN INTERNET CONNECTION just to play a friend, or my cousin who lives 3 blocks from me... Isn't that why we pay our Internet providers?
Also, The graphics are definitely better on PS3, PLUS it plays Blu-Ray player.
