Yes, 'Console' war. Don't class PC with the consoles
All jokes aside, I just prefer PC for shooters. The control is so much better and honestly the online play on consoles involves a lot of kids or very young teens that really aren't that good. Its not the speed of the aim or anything, they just don't play as well. I played BlOps, BF:BC2 and MoH on my PS3 and BlOps on 360 and I was constantly at the top player for the match. On PC I'm normally top half, rarely first.
Secondly, I like being at my PC. I can do everythign from it.
Thirdly, PC games are cheaper in stores usually $20 or so and now with Steam that goes down to $50 cheaper than buying a console game.
The graphics are usually slightly better and the game runs smoother (Crysis 2, Brink).
Internet connection is better because of the ethernet cable.
CD keys can be annoying and games not running or some error or what ever can be a pain but my PC can be upgraded every few years (a few hundred dollars if I shop around) and still run games (low settings most of the time if a few years pass).
I used to be a console kid but I played Half Life 2 on my PC and was addicted.
I did pre-order Arkam City for my 360 though.
