Well, i can only post my experiences with the original competition pro, and it was awful to play with it. I ended with my hands aching because of the bad ergonomics and have to switch hands constantly because the pain. I used it on amiga as well as on msx and for me it is the worst joystick ever designed. If you like sticks, go for a arcade one, like the telemach 200 and you will be in heaven. If sticks aren't your thing, then a megadrive pad with joymega-like adapter and let the enjoyment begin!
