I also agree that the N64 controller is actually quite good. The biggest issue is definitely the joystick wearing out, but the rest of the thing is quite normal to good and the Z button underneath is actually genius.
My problem with the controller was that the analog stick stuck out too much, was too hard, and had those plastic ridges. It always made my thumb sore. I remember I would put a waterproof band-aid on it just to act as a cushion. Also my hands were too close together when I held it that way. It felt awkward.
The N64 had some great ideas and innovations, but the execution was off. The Gamecube confirmed was so much better.
