To each their own, but yes, personally I find the UX of Mac GUI applications to be generally a lot more appealing compared to the alternatives available on Linux.
These projects were developed by volunteers and are distributed free of charge. No need to be a jerk.
Plus if there's something you don't like you can always pull the code, modify what you need and submit a pull request.
I use Linux everyday and I prefer a slightly off UI once in a while than having to deal with the frustratingly sluggish performance of macOS.
