Honestly how I feel right now, well kinda. I was using fedora silverblue but apps kept crashing and shit just wasn't working out how I wanted. I was excited to try VanillaOS until I did... It was annoying. I was hoping for a system that made it so I can seamlessly use dnf, pacman, and apt in the terminal and it would figure out all the containers for me but not at all. VanillaOS was too much of a hassle to keep track of everything and was just eh. I got fed up enough so I just installed NixOS today and so far I'm loving it. It's not as hard as I thought it would be but also I'm not doing anything to advanced yet. I plan on messing around with home-manager later. So far NixOS seems like it's exactly what I was looking for but all this time I avoided it
They have two. If the complaint is that neither wiki is as rich as the Gentoo or Arch wiki, consider that perhaps NixOS users don't need as much supplementary advice for configuring their systems.
