When I was young I was mostly using Windows. For the last 15 years or so it has been macOS. I made a number of attempts (sometimes lasting months) to use Linux but it never stuck. My conclusion is that usability is mostly about getting used to how things work and a tiny bit of customisation. There are no significant usability differences between operating systems. The _only_ thing that I have never gotten used to and that keeps slowing me down is that app switching (Cmd+Tab) in macOS is MRU while switching windows (Cmd+`, Cmd+Shift+`) within apps is circular. I'm finding it impossible to remember whether I have to go forward or backward to get back to the window I'm looking for within an app.
