Windows 11. Just upgraded from Windows 10 about three weeks ago, and it has been pretty smooth. Via the use of ExplorerPatcher and ShutUp10, adjusting the GUI and privacy was a snap.
I use Windows because I want compatibility with lots of software, and honestly I dislike trying to troubleshoot. Linux seems likely to be a huge pain in the rear and not allow me to play obscure games, along with just being mysterious in general. The big downside with Windows is that consumer versions of Windows have weaker privacy, while Education and Enterprise can't be bought by individuals. If given the opportunity, go for Enterprise.
