#nixos users, what's your favorite thing about it?

I installed it on my second laptop yesterday, then went running back to #endeavouros for now. My curiosity has been piqued though.

Observations:
- declarative system (users, packages was as far as I got)
- homegrown, but hard to learn configuration language
- #NixGui is the only configuration GUI, but didn't launch (crashed) for me, even after enabling #nixflakes

Two very interesting flows:
- desktop setup as code
- reproducible environment

> Use #NixOS Without Coding
> #NixGui is a configuration management tool designed for those who haven’t mastered the (arguably difficult) #nix language. It is also an attempt to replicate the ease of use of popular configuration systems
