Os choice is driven by your needs rather than any ideological mantra.

If your programs run under linux then go for it. I made good experiences with ubuntu. It simply works on my desktop. Gaming works. Most devtools work even better. Browser works too. Streaming is meh. So you can save a buck with the lower bitrate.

Whats holding people back is windows specific software that runs poorly under proton and wine. Like autodesk stuff.

If you figure out your usecases then you can evaluate it its worth switching.
