So. I have 2 I hate.
I had this old gamesube one for the switch. It was a wired one by powerA. Buttons would get jammed, accidentally broke the stick by leaving it in a bad position overnight (my bad) the cover of the cstick randomly slid off (had to glue it) and the while thing was hollow.
Also, I have a keapster explorer and the dpad is awful. Sometimes it jams to the left but its just a plain bad dpad, no physical feedback at all
Worst controller? Eh, I have controllers I don’t like. N64 controller. Original Xbox controller. Dreamcast controller. But are they the worst? Idk. Maybe I just didn’t have a whole lot of experience with any of those (didn’t own any of those consoles).
Maybe the Wiimote. Like I get the idea, but as a dedicated controller, meh. Same with the Switch Joycon; maybe even more so. I have a Pro controller because the Joycons just don’t cut it. When they’re attached to the Switch, they’re OK, but not as individual controllers.
