I've been using Fedora+KDE for over a decade, Windows 8 was last version of Windows I had installed at home, and we all know what a squarified mess that was.
Gnome is fine, but it's just not for me.
For everyone on here that complains about Windows requiring an 'online' account, MacOS does as well, but the perception is different. MacOS, just kind of quietly does it, with no ceremony, but Windows does a Ballmer-esque right-in-your-face demand. I couldn't possibly comment on Windows 11 as I've yet to use it, but Win10 felt a lot worse than Windows 7 which was probably the last high water mark for Windows after Windows 2000.
Afaik, you can choose to not sign into icloud when creating an account on your mac. It's not a hard requirement like it is on Windows, though they do obviously strongly nudge you to login to icloud.
At least on the latest Sequoia, there has been no hard requirement for an online account. They nudge you towards it, but you can decline and continue. As far as I can remember, macOS has never required an online account to set up a Mac.
I only use KDE, though it has weird instability from time to time. They just changed which gcc version I'm on so I am not sure if I've noticed the same instability or not. Overall though KDE is the perfect DE for me.

This has never been my experience. Is that new in Tahoe?
The Mac 100% does not require you to sign in to an Apple Account to use it. You can go about with a local account only just fine and you can easily do it right from the OOBE setup UI — no tricks involved whatsoever.
Plasma 6 is really polished and simple. I think anyone familiar with windows would be able to grab and run with it immediately.
No hate for anyone that likes other desktop environments, I as a long time windows user just really appreciate how familiar KDE feels.
