Funny how the most stable-over time OS I've ever used is Arch Linux. I had it running on an old netbook for almost 10 years, until they ended support for i386. I also have a laptop running Arch since I bought it on 2018, so it's been seven years. Never a clean reinstall on any of the machines. Just the usual upgrades, which in Arch means running the package manager every once in a while, and following upgrade guidelines in the rare occasion there's a need for something a bit more involved (90% of the time is simply installing reinstalling a package).
