Isn't it just what you're used to? I recently (2 years ago) went the other way - from Windows to macOS - and I feel the same way as you but in reverse. I'll never buy another Mac, and I can't wait to get back on Windows, but I know it's not because macOS is inherently bad. It's because I have over 20 years of Windows knowledge and despite it's flaws, I know it well and I know nothing of macOS.
There's plenty of quality on Windows, and Windows itself is a very good OS. It's just what you know, and what you're used to.
Indedentally, in over 20 years I've never encountered a show stopping problem, or kafkaesque hoops I've had to jump through. Maybe our definitions are different...
