I learned long ago that I hate playing FPSs on consoles. The speed and accuracy of a mouse is so much higher than that of an analog stick that there's no contest here.
The only advantage of a controler comes when moving your character, where the analog stick is superior than WASD, although the keyboard makes yup for that with the extra buttons that make things like swith weapons more easily.
On that regard, I've always wanted to try a gaming keypad to get the best of a keyboard and a gamepad, but they're expensive and have to be configured to properly work.
Please excuse my bad English.
