Spoken like someone who does not know Windows. If you buy a machine that comes with windows, and just use it off the shelf it, is a total mess as you say. (As well as probably loaded with crapware)
If you know Windows youre gonna install LTSC on that machine and have a nice productive time.
I am curious, do you buy a mac and just use it for work without any setup, off the shelf? If so that is a point in its favour I guess.
Also as someone who only knows Linux and Windows and is not familiar with Mac OS, anytime I have to use it, it is a baffling experience, common things are done with gestures and keyboard shortcuts that one would never be able to intuit or discover.
I find some random completely new Linux windows manager that Ive never seen before much easier to get to grips with than Mac OS.
