Apart from the look and feel, there are severe regressions with the operating system in a lot of places – external non-Apple hardware that would just work just fine on the existing OS stops working with a new OS version, etc. The quality of their OS has gone steadily downhill over the last few years.

At this point I would never do a macOS update unless I'm forced to do so for security purposes. I can't even begin to fathom why anyone installs the beta and does free QA for Apple.

I get the impression everyone at Cupertino works with only Apple Cinema displays and a lifetime supply of insanely priced Apple hardware; and no one bothers to test out compatibility with third-party devices at all.
