Both. I'd prefer Linux because it respects me as a user, but unfortunately too much stuff constantly breaks to fully convert. The moment I can play Assetto Corsa with all my mods using my wheel in VR I'll consider fully switching. Many other games already work though, so I'm slowly converting to using Linux as my default and Windows as the exception instead of the other way around.
Forgot the number, but one of the most common Logitech ones. Right now I'm not even getting past the first hurdle though, which is getting Assetto Corsa with Content Manager and mods to start. I spent a few hours on it and then decided that I had better things to do with my time
The common Logitech steering wheels should work if you have the steam-devices package installed on your system. Alternatively you can get the necessary udev rules from the oversteer repo: https://github.com/berarma/oversteer/tree/master/data/udev
(oversteer is also pretty handy)
I'm on holiday right now but I can get back to you on how to get Assetto Corsa with Content Manager to work.
