I personally think Nix OS brings some amazing features, very few of which are relevant for me as a regular laptop user without my own server farm. Sure, reproducible builds and dynamic package versions are neat. But if it takes me 1000 hrs to learn how to write a functional config file that I now have to keep updated, if I have to work with some weird repository, there is no documentation and community infighting… Nah, I’ll stick to debian (BTW) for a while.
