I also think the console versus PC thing is fucking stupid and should be left alone.
I play PC and console games pretty much equally. I would never dream of playing an RTS on my PS3, or a FPS on my PC. In my personal experiences, each does different things better than the other. Arguing over which is better is pointless and idiotic.
Why would you want to play a FPS on a console rather than PC?
Uniform server experience, easier to play friends in a face to face set up. Depending on how you go about yer multiplayer, easier time playing with friends across the net. Xbox invite system is quite smashing for bringing in friends either in the game you are playing or the very next one. Less trouble shooting too. (This one kinda of goes in with uniform server experience.)
I agree, that a mouse and keyboard set up is a superior input model for FPS, but I only see that as mattering when you're playing in a competition, and only if you playing cross platform. (Which I'm pretty sure does not happen in any official capacity.)
If your in a competition, and its via console then the aiming nudge is a none factor, as its equal for all sides. There are still noticeable skill differences between console FPS players.
An aside, Halo: Reach aiming nudge is very noticeable, and forceful. Its been the cause lowering my K/D ratio for more then one game. 8/
In my years of playing FPS on both consoles and PC, I've had a /much/ better playing experience via the console then the PC. The ill repute reputation of console vocalization, is an exaggeration. Its not that common, and most games offer a mute button for those few/rare individuals. Whereas I've experience grieving far more often on PCs, dick mods, crappy servers and arbitrary undeclared server rules. (One that I can remember clearly pissing my off some ten years ago in a Counter-Strike game, was that you randomly became a hapless low HP chicken for the rest of the round.)
These issues can go away once you find some good servers, but for myself this seems to fight against my casual nature toward the FPS games in particular. I generally play them to more or less have something to do, or keep myself occupied as I listen to a book on mp3.
Please don't take this as a herp da dur console iz better. Its just my antidote as to why I prefer FPS on consoles over PC.

Another aside:
How does this sound for a t-shirt?
You have a K/D ratio only a mother could love.
