I prefer my games on the PC, perhaps because that is all I have ever owned. I don't really see much reason to own a console as opposed to a PC. I can upgrade my PC, games are (most probably) going to keep working and it serves for a lot more than just playing games (never mind the great input method that is the keyboard). The argument about the controller being better for some games also doesn't really hold much since you can use a controller for the PC (and HOTAS, etc.) if you wish.
The only argument I can come up in favor of consoles is that their hardware tends to remain static through the cycle so it's easier to get the best out of them, and it could be cheaper to develop for them (no need to try many hardware configurations) but as a consumer there is very little reason. And I haven't even mentioned modding.
Couldn't you play said games with a controller on the PC, instead though? Assuming the game supports it on PC, that is.
