Most people cant get over the differences in the games nowadays, and controlers, and Hardware. Just buy both. i prefer my 360 over the ps3, but the ps3 has a few good games. their both good
Ps3 Id rather the PS3 cause it has better graphics then X-box 360 and most other consoles, and it can be used as a mass storage device, + a blu-ray player and with the internet, for PS3 it is free, but with the X-box 360 you have to buy " live points " to go on internet
