I'm gunna have to say my 360. Although I don't really play all that much. I pretty much have to have absolutly nothing else I want to do.
I orginally Got the thing so I could play the first Rainbow Six Vegas game with my friends. But pretty much no one really plays anymore any of the games. So everyonce and a while I'll pick up Rock Band or Amped3, more rarely Vegas 2 or COD4.
I can't really bash the PS3 I don't have any real experience with it but I do hear my fair share of complaints against it. At first it was about them blowing up kind fast and then I heard that the online was kind of weak in comparison to Xbox Live. But like I said I have no personal experience with it so I can't really say.
