The PS controller is not. The right joystick is in the correct position, but the left is not.
I don't even know why people complain about the position of the left analog since the left is used for broader movements in FPS games whereas the right is used for much finer movements such as aiming.
I would never reduce myself to playing a FPS on a console, so maybe I'm out of my element.
I get that head to head KB/M has the advantage, but 99% of the time you are facing other KB/M users and same with controller users.
