It depends on the game, mostly. With a game like GTA, I think it's a bit easier for me to get it for console, since it's a better sitting situation and for me to look like an idiot, as I then try to do what every gamer does: Turn the controller, shake it, or button mash harder to do things more effectively. (Doesn't really help, but it's an instinct thing when you're immersed in it.)
However, I think for my fantasy games mostly, I go to PC. Like with MMOs, Skyrim, Dragon Age and the like, I LOVE the modding aspect of games like that. (I think the only exception to the rule I make here is with Saints Row. I don't know why, but that game just FITS on the PC.)
