I’m with kyotokid on this one. Best controller by a long shot. Dreamcast & gamecube are 2nd with nothing to call between them. I’ve never known any controller to survive hard cosistent use for any amount of time. The sole exception is my original N64 grey controller, which still works perfectly.
I think the trident design was brilliant because it forced designers to consider how to use the pad, although certain standards did emerge. And the module slot at the back was genius.
