My preference of playing FPS on a PC comes from basically playing FPS for many years and it's the interface that I'm most comfortable with.
We are talking way back to the days of the original Wolfenstein and Doom days.
I find it difficult to adapt to a different inferface, such as the gamepad for such games.
I mean racing games and platformers are fine, I just cannot get into playing FPS on a console at all.
Sadly, Infinity Ward have messed up and ther is a lack of dedicated servers for us PC gamers, but we are still hoping that IW will change their stance on this.
There's nothing worse than being in a middle of a Killstreak and suddenly during the firefight, the host migrates.
On a plus side tho, I do like the fact that it's easy to assemble a team and join a game.
