Weird coincidence, I was asked by multiple friends recently about which controller they should buy too.
Official controllers (ie Xbox, PlayStation) are usually good but many 3rd party controllers tend to be better for PC. Specifically you’re looking for one that has hall effect joysticks, which makes the sticks last way way longer and are of better quality. A lot of these companies also have special software for PC to edit deadzones, profiles, macros, etc.
The best controller on the market IMO is the 8bitdo pro 2. It’s comfy, well-built, works for ages, and has replaceable batteries.
