For me and a lot of others what I really want is a UNIX that just works.
Meaning it just works with its hardware in all ways... audio and video playing, recording, editing and everything else all work very well, without having to recompile the kernel or hunt down and install alpha drivers without source hosted on sketchy sites, which is what drove me away from other UNIXes.
Also macOS is a good platform for developing native iOS apps. Why iOS and not Android? Mostly because the version adoption curve of Android is pretty bad.
The point is it's more about functionality and getting stuff done than it is about pretty. With other UNIXes there was always too much fighting with the system.
