I’m not quite sure why people are still worried about the stability of btrfs when it has been rock solid for years. Synology has been using it for quite a while now in their NAS systems, they surely wouldn’t if it’d mean a lot of customers were at risk of losing their data.
There are valid reasons not to be using btrfs (although I’d argue most ordinary use cases don’t have a valid reason), but stability certainly isn’t one of them, independent of the distribution used (unless it’s ancient).
