Linux kernel is just waaaaayyyyy better than Windows, at this point. Better hardware support, better stability, more features. And it keeps getting better.

Windows kernel is not _bad_, but it's developed by far fewer people.

Linux also has systemd with its unified system resource management. I can slice and dice my system as I want between containers. Oh, and containers are also awesome (Windows has them, macOS doesn't).

Desktop environments are a matter of personal taste. I like my DE very minimal: status bar, quick launcher panel, and that's it.
