I would say at this point in time MacOS is a superior OS for laptops but inferior to both Windows and big Linux distros for desktop. Windowing is awful, multi monitor support is inferior, the OS doesn't even have native support for mouse 4 + 5 buttons, and there's no subpixel text antialiasing which makes fonts look awful on 3rd party monitors. Beyond that, the lack of Nvidea support and OpenGL support makes it a poor platform for desktop 3D modelling and games.

This is a personal anecdote, but I also feel like the quality and robustness of Mac OS has declined compared to the direction of Windows or Linux over the last few OS upgrades.
