A lot of it has to do with experience. Linux is definitely rougher around the edges than Windows and OSX, but it also allows you to be free to do what you want with the OS as a hacker or programmer. Also I don't like being tracked while I'm on my computer. OSX is much better than windows in that respect so I'll throw that out there for the record. Windows tends to be more opinionated and tries to bind you to it's work flow and update schedule. On linux you can have your system update everyday or once a year; not recommended but if you're airgapped it doesn't really matter. I choose freedom over walled gardens. I still play games on windows though, but that's the only reason :)
