Yeah, but I find that particularly with laptops, even with LTS releases, there's almost always something you need to fix.

For example, there's a weird quirk with my laptop that if I am using a USB keyboard and stop typing for more than a minute, it "powers down", and if when I start typing again it misses the first four or five characters, which is very annoying.

The solution involved putting a few boot parameters and then it works fine and as expected, but I would be reluctant to do that with Ubuntu or really any non-NixOS distro, because if I screw up a boot param I get into a situation where the computer won't, you know, boot, meaning I'm stuck screwing around with grub commands and trying to fix things, which is annoying. With NixOS, if I screw things up it's like a minute of rebooting and choosing the old generation.

Not to mention that if you have a non-declarative OS, it can be hard to know what exactly is on the computer. When I ran an Ubuntu LTS server, I eventually had installed dozens of packages that I don't think were being used but it was hard to know for sure which ones were necessary and which ones weren't. When I'm using NixOS all the packages are unambiguously in the configuration.nix. "Uninstalling" a program (including its transitive dependencies) is just removing that package out of the configuration.nix and rebuilding.

I have nothing against LTS releases, but I do think that at least for laptops (which can have kind of arcane hardware quirks) it's better to use NixOS.
