Arch stable ? I mean, from experience, I've had one break in stability so bad it made me hop : the lack of gentoo-like config protect. To be fair, I was on Artix but the breakage was versions of Pipewire deleting not just my changed config files but config files it couldn't run without ! Or to be fair, also, actual Arch but on my phone, plasma 5 package conflicts (that came as is from the installation image) prevent the whole system from updating 🙃 ... Never had any of those 2 problems on OpenSUSE or, to be fair, non-Arch-based distros
