I have better things to do then have a "vendetta" against either a corporation or a piece of equipment (I don't know which you were insinuating).
At the same time I have no reason to defend commercial entities that should do better.
Like I said, I use the goddamn thing (SP3) as a daily driver for mobile use. It doesn't change the fact that numerous things have been appallingly broken for a stack completely controlled by Microsoft. I absolutely do not care to enumerate the "quirky behavior". For that you can go to answers.microsoft.com and also get a laugh observing that shitshow of unhelpfulness.
Apple help for MacOS stuff for example is hilarious from official or major communities. They treat everyone like complete newbies.
Not being too used to Ubuntu except for production servers, I was never able to resolve getting it to work on my Touchpad back in 2010 nor getting my VM to update from 14 to 16 without screwing up. From my pov, in aggregate, all the OSes have their issues
Why not sell the SP3 and get anything else? No one should use something they dislike this much if it isn't mandated.
You seem to dislike Windows quite a bit. To the point where it seems personal or you have a vendetta against it.
Yes things like settings are silly in modern Windows. But they aren't make or break stuff.
There's major positives to be seen from Windows too. They are the only major player trying to get touch working on desktop. That's not easy to do.
You don't specify what sloppiness or "years of varying quirky behavior" so I can't say much about that. If I wanted to really criticize the other OSes I have experience with - MacOS and Ubuntu. I'm sure I could come up with sloppiness issues and varying quirky behavior too. It wouldn't be hard at all, but it wouldn't be right either. They are both solid OSes overall (at least for now).
