Steam

Because they're all shit, each current controller has some kind of downside when wanting to configure it for games.

Either Steam input doesn't recognise extra buttons, or the ones that do have issues with being Bluetooth only.

I've tried the vader 3 which was great, but unrecognised so needed extra software to remap for each game which was never as simple as steam input and required me to use a mouse and keyboard which isn't great with a htpc setup.

And then recently I've tried the horipad for steam, this is almost perfect except for only two back paddles, the face buttons being weirdly shaped so the some of them stick when pressing them and the Bluetooth is shitty.

If steam input allowed the full use of generic controllers instead of ones that have been explicitly set up, I'd have no issues, I'd be able to find the one for me. But because they don't do that, I'm waiting for the steam controller 2 because a full layout just like the steam deck would be the dream.
