MacOS is unbeatable, and it is unix. I still have my first macbook from 8 years ago, as a unix server now. I had another for 4 years which I sold. And the last one I got was a used macbook air 2013 model with 8gb ram for $600. They last in my experience but hardware quality IS debatable.

windows 10 has "subsystem for linux" so you get a virtual linux environment with bash, so maybe my argument isn't as strong now. Still I don't think windows would match the user experience for me anyways.
