I've never had to experience any of the
really terrible ones, fortunately. My least favorite of the ones I've used—NES, SNES, N64, GameCube, Wii Remote, Wii Nunchuck, Wii Classic, Wii U GamePad, Wii U Pro, PS1, PS2, PS3, Xbox 360, Ouya—is probably still the Nintendo 64 controller, though I really didn't like the Wii Nunchuck controller either (I seem to have a stronger dislike for that one than most people, actually). The Wii in general was kind of garbage for controller options unless you found a game that supported the Classic Controller; even the normal remote had too few buttons and was too small without a cover for me to feel comfortable with it, and I remember having a tendency to hit the B button accidentally when playing Mega Man 10. (Though I think that game actually does support the Classic Controller? I'd have to test it.)
