I switched to guix and haven’t looked back.

Mostly because:

1. I like the idea of functional package managers
2. I like guix’s dedication to making every package buildable from source (thus the no non-libre code rule)
3. I like the expressiveness of scheme vs Nix’s package description language

Guix is the smoothest time I’ve ever built packages for a distro before (well outside arch). Which is good because there’s a lot of out of date and unadded packages for potential.
