gaming online is free unlike xbox live where you have to buy a gold membership to play online
PS3 controller has built in battery
the PS3 has a wireless network adapter built in unlike the 360 where you have to spend an additional $100.00 to get one for the xbox 360
also the PS3 has a lower fail rate than the 360
the PS3 has a bluray drive so you can also play bluray movies on it with no additional hardware or software.
the main reason i bought my PS3 was because i was scared off by the high fail rate the xbox 360 has but i do not regret getting a PS3 over an xbox
