I really like OpenSUSE. I run Leap on one laptop and Tumbleweed on another as well as my desktop. The Leap system I installed at 42.1 and have since upgraded all the way to 15.4 without anything breaking or the need to reinstall from scratch. I don't do very much with that machine, to be fair, and I don't have a very large number of packages installed on it, but with that in mind, it has been very stable over the years and not given me any trouble.
I am not sure if I benefit in any way from Leap and SLE having a shared code base, but I see no downside either. The version number of the kernel is a bit dated, but AFAIK, with enterprise distros that doesn't mean as much as it would otherwise. I have not noticed any features missing I wanted to have/use, let's put it that way.
A real shame about the timing too. I understand the general reasoning behind it (it sounds like SUSE internally is moving more towards the container/MicroOS focus) but making such destabilizing changes right when people are really looking for RHEL/CentOS alternatives feels like such a missed opportunity.
