I’ll echo this sentiment. While it may take a while to figure out how to do something initially, the great thing about NixOS is that you only have to figure out how to do it exactly once. As far as my main desktop OS, I figured out a config that I liked several years ago, and haven’t really tweaked much since then. I ran the rolling release for a while, but I’ve moved back to the stable release, which is… well, stable.
