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
Fuck joycons
All the cool kids hate Joycons.
Seriously though, I replaced them immediately and never took them out of the drawer again.
I used them for s bit before I got something better. The sticks have less travel than a fucking 3ds slider
