The sad truth is that most software sucks, regardless of the license, there's just a lower barrier to entry, use, and discoverability with OSS so it's more visible. At least with OSS we can fix the issues instead of just accepting the suckage.
After a year I find the only advantage of OSX are browser with touchpad gesture experience and windows edge handling. Haven't tried any distro ever since switching to MBP, wayland might have a better chance of replicating the experience. Hoping for the camera driver to be done.
In Linux everything else is better, fuller implementation of base tools, customizability, no crap like /var/folders..
This is entirely subjective; it is not a wise comment to make because it is better FOR YOU, not for everyone. For me, I liked the configurability in Linux desktop land but there comes a time when you want to sit in your office and get stuff done instead of spending all the time moving the furniture around and decorating; OSX doesn't let you do any decorating or move the furniture, so you're forced to do work (to some extent).
I daily use Linux, yet my day-job is to write software on OSX and Windows, so I get to use every system every day. They're all pretty much a muchness.
Great for servers.
Basically, each to their own. None is "better".
