I have used nixos for about a year. Before it, i had used archlinux for about 8 years and ubuntu about 3years.
The most advantage of the nixos is its safety mechanism. it saves all package in hashed path, and make symbolic link to users' profile. as well, it saves every version of all package installed. as a result, you can roll back to the past version, if you meet a kernel panic.
bye to the update hole of archlinux. bye to the worry of online update for a working server.
It also support multi-version of a package. the coder would take advantage to it. you will never to worry about the mess of you developing environment.
Nixos is built by a configuration file. you can write once and rerbuild as many as you wish.

the below is my basic configuration for my qemu vm

Will comment my opinion on it later.
