I'm one of the converts. Didn't like Windows 11 at all, decided to try Ubuntu/Zorin before going back to 10 and ended up staying. I've tried various distros many times over the past ~15 years but it never felt "ready" to me until now.
The last few years have had great improvements. For any average user (like a kid or adult that just browses web, streams video, zoom calls, etc) there is no reason a Linux desktop can't be their main system.
