I don't really know of any FPS that are the best of the best that aren't on consoles either though and I think the reason you would rather play games on the console like dark souls (currently playing daemon's souls on ps3) is because of the controller, but you can use a pc with controller, for now it's a little more difficult with settings and what not, but there is software to do the exact same thing.
I agree about pretty much all the big FPS games being on consoles too. As for Dark Souls, the PC port is just plain bad. You can use a gamepad on PC too, by the way.
