The magic sauce for desktop users is home-manager, which allows declarative setup of your user environment. And rollbacks to previous generations with one command , in the OS or the boot screen. I use it to set up my window manager, fonts, Vim/VS Code/Firefox plugins, configure all my tools, set up user-specific systemd jobs, ... I recently got a new laptop and I had my perfect setup in 20 minutes (install NixOS, git clone config repo, add new machine specific config (disks), apply NixOS config). I appreciate that it's not for everyone , but it is brilliant.
