When I used Bazzite, I had it on a samsung laptop and on my steam deck, both worked perfectly for the handful of months that lasted. It integrates seamlessly with steam's updater so apart from updates taking longer, you wouldn't be able to tell it wasn't vanilla from gaming mode. Layering my own packages on top was painless and worked fine too, I particularly remember using tailscale that way. Overall it was rock solid and hands off, most variants keep themselves and flatpaks updated on their own and whatnot.

I came from vanilla stramos and I had it on my laptop as soon as I got it. On the desktop side, I hadn't moved away from windows 10 yet, and by the time I did all my devices were already on NixOS. All in all if nix's declarative approach didn't tickle my nerd bones so perfectly, I'd probably be all in on it to this day.
