Windows (and DOS) user. I’ve tried various flavors of *nix over the years, but have never liked any so far—Mint isn't bad. I use Armbian on my Orange Pi web-server.

As a low-level programmer, I can appreciate some aspects of *nix like the command-line tools such as grep, sed, and awk (these are exactly the kinds of tools I frequently write for use—and fun). I also like regexp very much—I once wrote my own powerful text/string parser a long time ago before getting some Windows ports of the aforementioned tools.
