I used Gentoo for ten years (2005–2015), and I was very happy with it! Stable was not the word I would use, in that updating frequently broke and required manual intervention. But it was so flexible! The easily accessible options one has for choosing everything about the system is unparalleled in any system I have tried since. I would still use it if I had more tinkering time. These days I am on NixOS, mostly to have the same setup on every machine I use.
I've been on Gentoo for my gaming desktop for like 2-3 years now and I don't think I've ever had an update break anything.
I will say though that my valgrind is broken due to march native. :)
