Manjaro isn't that fragile on its own. No, seriously, their goal is to make a stable version of Arch. No wait stop laughing —

The majority of issues with Manjaro itself (notwithstanding the team's other issues) would be fixed by retiring the AUR as an official software source altogether. It simply isn't a repository built with Manjaro's slower burn in mind; it demands a bleeding edge system. If you don't use the AUR, Manjaro is as stable as any other system. It just sucks for many other reasons, which is why I personally wouldn't use it.
