The main thing is that the PS3 is more expensive. Poorer and/or less refined tend to go for the cheaper console. When the Xbox 360 first came, I got it and the community was very nice. People tended to be helpful, respectful, and left cursing to just in game when they got killed, not before the game or in the post game lobby. Then I put in Halo 2 and the very first words I hear upon joining a match are every single curse word in the human language. It also doesn't help that everyone is in party chat. It tends to leave you with the screaming 8 year olds.
