My Gameboy Collor pawns both.

I don't own either one, though I'll be getting a XBox 360 soon. My uncle bought it for me, I would go with PS3 if he actually asked for my opinion, but who am I to moan, I'm getting XBox 360 for free.

As to why I prefer PS3, it has better exclusives (right now I would kill to play me some Gran turismo 5, and Heavy Rain), more variety, and free online play. Graphics are least important, to me anyways, and both controlers feel good in my hands.
