I use them while PC gaming, since I don't really console game as of late!

Never tbh.

Never

I have an NES pad for the PC that I got specifically for playing SMB3 on an emulator, I think I also got an N64 controller for the PC to play F-Zero X on an emulator (it's better on the console, which I don't have; it lags occasionally on the PC), and I got an XBox One controller to play GTA 5 on the PC (I had gotten a PS5 controller before that because it's supposed to be the best, but I couldn't get it to work for the PC). But I've hardly used any of them. :P

That depends if you consider handheld PCs as a "gamepad"
