I haven’t had any issues with controller support in any games, just the same as using an Xbox controller.

There is no native Linux software, so I use Winboat to run the software. You could also run it in a VM.

I only have the black controller, so I can’t comment on the white on

I have larger hands and have the Cyclone 2. Fantastic controller and my daily driver. I didn’t like the clicky face buttons but they’ve grown on me. Happy to answer any questions. No real issues across Linux or Windows.

For me Booklore has better metadata management

If you don’t want to self host, they offer hosting.

Their unifi controller container is definitely one of the more popular ones.
