I use KDE as a daily driver at work, privately run windows 12 and maintain six modern macs at my workshop. Of the bunch KDE is easily the best, with the least amount of weird unexpected behavior and the most logical, user-centric way to lay out and present system setting. Windows 11 feels like an archeogical research trip into the UI paradigms of the past every time you need to change the settings, and macOS constantly does things you didn't ask it for and disallows/breaks things you did for the past years. And there are small things like: After every software update I have to manually put shortcuts into the dock again on six computers. They make it harder and harder to run software that hasn't been approved by apple. And the small UI papercuts are easily worse than on KDE (I count here stuff that clearly didn't work as intended, not stuff I have opinions about).

Correction: Windows 11, that was a typo, sorry.
