I like consoles because the games are made especially for it, so there's no worries about games not working properly, and because in my opinion, controllers are better for most games, but not all.
But, I like computers because they can do as much as consoles and much more, and it means I don't need to move to get my gaming fix. Also, for some games I can use controllers, so that's useful.
But, consoles win overall, because I prefer to have an experience tailored exactly to what I'm using, and the fact that everything you can get for it will work with it, so if I see a load of games I want for sale, I can just buy them instead of finding out whether they work with my PC. And not all PC games work well with my PC, even if they say they do. A good example of this is Arkham Asylum. It's still enjoyable, but even with the settings right down, it lags worse than anything else I've played.
