LOL That was good.
I just think the best combo is this:
movement: small stick style joystick ( because you use a few fingers rather than perhaps 4 fingers for W-A-S-Z)
Looking around and aiming the gun: mouse
The mouse (or your moving your hand rather is much faster than using fingers to manipulate the other joystick for xy axis movements because it only requires you to move the hand while you can fire with the same hand. The joystick requires you to move fingers and take your hand partially off to use those 4 buttons.
