I've been distro hopping for months now and found openSUSE the most stable and bug-free experience out of the main distros. I'm not sure why it isn't mentioned more often. People think more bleeding-edge distros have more bugs but I've found that to be the opposite and even IF something went wrong, it is automatically installed with a snapshot rollback feature!
Oh I like OpenSUSE! Been a while since I used it though. I've been meaning to look into a few things for that distro such as its secure boot implementation and mandatory access control defaults, but I've just not got around to it.
