If we factor in failure rates, definitely the Valve Index Controllers.

I fucking love them when they work, but this is the second or third time that I had to get one replaced by Valve in the 7 months of having them. Please, Valve, Index users are already paying premium money. We'd like controllers that don't just stop working properly despite NOT having hit them against walls repeatedly or anything of that sort. It also can't be super lucrative for you if for every sold pair you create and ship out 5 replacements.

I remember trying a Terminator joystick at a friend's house on his C64. That was a very bad controller.

I haven't used much controllers but I don't like the xbox controller. It doesn't get too comfortable to grip after a while and it doesn't react well to sweat.

I've played an Atari Jaguar before. Those controllers were fucking awful.

The 64 controller is a close contender, although it's hard to give it shit when it was from when 3D first started being a thing and nobody really figured shit out. But I mean, it should have been a no brainer to not design it so you'd need 3 hands to comfortably use all the inputs.

If you mean specific brands and what not; I can't even remember all the garbage 3rd party things I've used throughout my life. Not good enough or terrible enough to even remember.

Any controller using Bluetooth.

Every madcatz controller I've used has been terrible. Xbox, Dreamcast, and PSone. Just terrible.

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.

The N64 Controller is not one I miss, the stick was just... trash

I switched from Xbox 360 controllers to PS5 controllers (on pc). They weigh at least twice as much and the battery maybe lasts 4 hours if you're lucky.

Any controller that's thin and rectangular: NES, Turbografx-16, sega master system, or more recently the switch in handheld mode

Anything by Logitech.
