My work-issued Macbook Pro regularly forgets which monitor (my external monitor or the built-in display) is the primary monitor and moves the dock and task bar between them seemingly at random.
My mouse sensitivity is cranked all the way up but my mouse still feels like it's mired in tar compared to my Windows and Linux machines.
The dock is always in the way. I can hide it when a window approaches/overlaps it, but it often takes multiple swipes with the mouse to get it to reappear. Completely removing the dock (which would be my preference) does not seem to be an option. I was able to move it to the left side of the screen, which is better - why take up so much valuable vertical screen real estate with a top bar and a dock on the bottom???
So... I don't know. I'm not seeing it personally. For me Gnome, KDE, Windows 10, and Windows all provide a better GUI desktop experience than macOS.
