I honestly hate the dualshock design. It's more about aesthetics then it is ergonomics. The controller was always too small for me and the thumb placement never felt right. I really liked the original Xbox controller and was pissed they never released a large version of their controllers afterwards. It was the only one that never gave me hand cramps after long sessions.

The N64 controller wasn't a good controller in hindsight, but it was an experimental controller, because like I already said, Nintendo didn't know how game devs would want to use an analog stick. The center was ambidextrous, so there were three different holding configurations. I have more issue with the Game Cube controller with it's analog nub. It wasn't comfortable to use ever and they should have realized that by then.
