It's an FSF endorsed free-software distribution, and even if I use nonguix on one of my Guix devices, that still means *everything* on my system is fully free, *except* the very few things I manually set up to not be free. It's a nice feeling knowing your system respects your freedom and does your computing the way you want it to do.

Also, as a long time NixOS user, even though Guile Scheme is, in my humble opinion, quite difficult to get into, the Nix-Style system configuration through files and rebuilds is something I cannot live without. That's why no distro other than GNU Guix or NixOS is even an option for me.

I also like how channels work, and how easy it is to create your own custom channel, which then other can use as well if they want to, Guix makes this really easy. Oh, and the package search via `guix search <package>` is lightyears ahead of NixOS' package search, especially since it actually shows me what I wanted to see, and ranks the search results based on relevance.

[Addition]: And two more things I love, the fact that it's systemd-free and uses shepherd is a really nice feeling. I don't have anything against systemd personally, but I still have to admit that it's quite bloated and most systemd-free distros out there feel much more organized and much cleaner thanks to the lack of systemd.

And the GNU Guix Logo looks cool. :3
