Console, mainly for ease of use. I can buy a console game knowing that it will work just fine right out of the box - I don't need to worry about system requirements, or anything like that. Which works for me, because my current PC is old and outdated, and I don't really plan on upgrading until this one dies on me.
Which is another point, too. Console gaming is cheaper. I don't really know how much it would cost me to get a gaming PC at the moment, but I'm pretty sure that it would be more than I paid for my Xbox 360 a few years ago. And, there's really nothing about playing games on PC that makes me think it would be worth the money. Maybe fan created mods for games I enjoy - but, that's not really enough on its own.
