@LittleTom the wii u pro controller is fucking incredible. i don't know what it is, but that thing feels so nice to hold. i unfortunately broke mine while opening it up to swap around the buttons for an xbox-like placing. the shoulder buttons on my controller had mysteriously short wires and snapped off when i was trying to put it back together. i never got around to fixing it and eventually lost some of the pieces at some point so i just chucked the rest :(
i like the ps4 controller too, especially with how much love it has been getting on PC recently with SDL getting merged into emulators and Steam Input having absurdly good support for them. 4-5 years ago you had to download relatively janky software to convert it into an xinput controller and if you wanted gyro you need even more programs to send the gyro data over a local address, and these days it often just works, gyro included.
never been a fan of xbox controllers, so i'm not a huge fan of the switch pro controller either. joycons suck ass, the dualsense feels horrible imo. the only other controller i REALLY like is the gamecube controller, and if i can use it for a game i will.
I may see if I can get a DS4 sometime. I'm desperate for another controller that's easy to get and replace because as far as I'm concerned the new xbox controllers are just trash and the Switch Pro has its own issues like 1. pretty terrible input delay 2. no regular (non HD) rumble, if you use it on pc it "works" but it's pathetic unless the game supports HD rumble and 3. sticks are flimsy garbage
And yeah, if a game is made for the gamecube controller it's just godlike. I love using it with Dolphin.
