Thing is, I prefer PC for one simple reason. A lot of the games I play require scrolling over large maps, accessing menus, submenus etc, selecting single units on the battlefield or single buildings in a city, point and click is, to my mind, the ultimate tool for that kind of game, I've never found an interface on the, admittedly limited, number of consoles I have used that have been an equal to it.
If I played games that were more oriented towards the console control style, then possibly I'd have a different opinion, but, for the type of games I play, I find the PC superior.
