+1 for Tumbleweed, it works so incredibly well. In the very rare case where an update doesn’t work out for you, you can easily roll back to a previous btrfs snapshot.
Fedora is quite nice, too, but I’ve come to prefer rolling distros over a release based one.
Kalpa / Aeon might be interesting, too, if your use case fits an immutable distro.
The absolute memest.
