Well it’s so different, but I can start by mentioning a single thing...

You know the feeling when you got a brand new Debian that you just installed with all your favorite packages… then a friend of yours suggests you should try somehting that’s not installed on your pristine OS but you can’t help but install it. Then you realize it’s not useful for you… at that point, and going forward, your Debian is polluted with libs you can’t uninstall easily so you live with the fact that they’ll stay there.

Over time, those things you try add up a ton of useless libs and you end up having to format your OS so you get back to that feel good pristine version.

With NixOS, you don’t even have to install an app to use it… it can download it, build it from source, execute it and trash it in a single command without leaving a trace behind. Once the command is done, you still have the same exact OS you had prior.

I have more to tell, but that’s enough for a nostr note, I guess.
