I've also used all three OS's in anger and largely agree.
I like to call that sort of attitude YOSPOS, named after one of the technology-oriented subforums on Something Awful. It stands for "Your Operating System is a Piece Of Shit."
Which OS? Your OS, whichever one (the royal) You happen to be using at the time. They all stink for different reasons, and it's just a matter of which OS's annoyances you decide to put up with.
That said, good lord, Windows 11 has been rough. I actually don't mind most of the UI changes, but the AI psychosis and the general lack of stability has made Windows 11 one of the only versions of Windows I can remember that started mediocre and kept getting worse with updates instead of better.
