Just because you don't like them doesn't mean other people don't.

As a kid I had no hope of affording the official PlayStation racing wheel, but I could afford the MadCatz one. When I wanted a 2nd guitar controller to play with friends on the PS2, NYKO offered a wireless one that was much better than the official ones. My first wireless controller, before the WaveBird, was a MadCatz PS2 controller that was fantastic.

I spent a good chunk of this weekend researching 3rd party JoyCons because the ones from Nintendo are basically cheap novelty toys that sell for $80.

8BitDo have been making quality controllers for several years now, and they have a whole section of their website dedicated to Xbox stuff. They appear to be licensed, so they will probably still be good?

Especially with how expensive 1st party controllers are, it can make a ton of sense to get cheap 3rd party ones. Especially if you aren't into hardcore or competitive games.
