I have Gulikit’s own controller with hall effect sticks, and they feel way smoother than other controllers to me. Since it’s all magnetic, there’s no feeling of friction or scraping of plastic against plastic that I immediately felt after comparing to my Series X controller. I guess a good equivalent would be an on vs off air hockey table. I haven’t tried their joycon replacements though, so not sure if the same feeling carries over to them. There’s not much of a precision difference, but you can get the deadzones down to pretty much nothing without any rogue inputs so it helps a little in certain games.
