I did a lot of distro hopping, but settled on OpenSUSE for a lot of reasons, but somebody suggested nixOS as I was sorting out a distro for my wife's laptop.

She is bad with tech, and her 2010 windows laptop was making her lose her temper; with how slow and intrusive stuff was when she wanted to do work, and updates altering things. Her wants were: speed and consistency, even if it died she wanted it back exactly the same.

So I setup nix, read about editting the config and rebuilds, and pretty quickly had a config that included zoom for her meetings, libreoffice for her client stuff, and browser. Had to add a hardware line for the WiFi card. Rebuild, and it is exactly everything she needs.

It is peppy like my brand new work Windows computer. Which is both a praise to nixOS and a slam against Windows degradation.
