I'm no console fan. I have a PS3.
I find the game choices for PS3 poor. They have a few good ones out their but mostly shooters or hack and slash. PS3 is an uber PC. It acts like one. I have a mouse and keyboard connected to it and runs its own OS and I can serf the net etc. Why they call them consoles anymore is beyond me?
XBox 360 has more choices and variety of games. Also a very friendly MS interface to Vista. I don't own a 360 because I won't invest in it. Before you wonder about my PS3 I also didn't buy it. Was given as a free gift for purchasing a Sony vaio laptop for my wife a year ago.
In the end of the day I would choose my PC.
