Ps3 hands down.

I've been a xbox360 fan boy ever since it came out and then I switched over to the ps3 and love it a lot more.

The controller is a lot better. The joysticks feel a lot smoother(for more precise movements) and its not massive like the 360s
Built in wifi (you gotta buy 1 for the 360)
Free online play
Blu ray
You can surf the web
nearly not as much system failures as the 360 (rrod)
A lot of ppl say the 360 online is better, but truthfully I don't see a difference lol. I've played the same game online for 360 and the ps3 and they are identical. If your talking about the extra shit you get like netflicks and shit then yea 360 online is better lol. The ps3 and 360 both have there own stores but I think the ps3s store is a lot more detailed and better layout (easier to find shit)

And for games, everybody has their own taste in games so you choose on that.
