Separating the OS itself from any feelings people might have about MS and their antics, I actually like Win10 and find it to be stable and fast.
Admittedly it still feels like a work in progress, with the GUI feeling unfinished in some areas, for example we have both Settings and Control Panel... the new and the old, and not yet amalgamated.
To the Win 10 haters, to paraphrase an old saying, you can't please some people any of the time
