Linux if you’re prepared to support it entirely yourself
What does this even mean? The most work caused in administering my company's IT comes from destructive patches from Microsoft. Just like a month ago they released a security patch that caused the domain controller to not reboot which is pretty much the worst thing you can run into aside outright malicious actors (not sure Microsoft doesn't count as one). So I had to "support" users by rolling back untested shit until a hotfix was released.
My private setup runs exclusively on Linux. Patches also sometimes cause trouble but it's just as infrequent and less destructive if it happens.
It's really not that different from an admin point of view but it's not Linux' business model to snoop on or extort you or to force proprietary hardware on you because sEcUrItY.
