+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.

There’s opi which does the whole search-and-add-repos thing for you, for OBS. Not sure if there’s something similar for COPR.

It’s still separate repositories, though, I’ll grant you that.

You’re going to end up needing a knife…

OpenSUSE, Tumbleweed on workstations (KDE) and Leap on my server.
