LFS (https://www.linuxfromscratch.org)! If that counts as a "distro". I've never had a system so stable than one that I built myself. Arch has been the closest to something I like that is an actual distribution. For a long time I struggled with the package managers on the popular distributions dictating how bleeding edge I could be. I want to build the latest and greatest versions of some projects before the package maintainers get around to it. BUT when I do that, the package system in whatever distro I'm on loses track of whatever I just built and doesn't count it as a dependency met for something else later. I get why this can't work.. I just don't like it. So I did LFS for over a decade.. but building every little thing from scratch and then keeping it up to date with every dependency along the way takes way more time from your life than you like when you have a job and family! So now I (reluctantly) live the distro lifestyle. If I'm looking to run a server, then I like the Red Hat based distros. If I just want to mess around, I like Arch.
