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 really issues across Linux or Windows.
