Manjaro - because everyone else seems to only be voting for Arch itself here. Manjaro is actually very stable, but I did sometimes have some trouble with AUR updates clashing. I like it because it stays relatively up to date and I don’t have to do any major reinstalls or upgrades. I’ve been on it for a few years and never have lost data or was not able to get it started (even if it did need a manual kick-start once or twice). Like any distro, over time you become savvy around what to use and what to avoid.
