I disagree. Things like the "natural" scrolling now activated by default in macOS which makes absolutely no sense with a mouse, for instance, and is really disorienting. The disappearing scroll bars by default, same thing. Thankfully all this non sense can be turned off, in order to revert to a time when macOS didn't tried to look like a tablet.
Whereas the GUI of Windows (except the Windows 8 industrial accident, which was a huge mess, to be honest) remained stable.
