I used both tumbleweed and leap for a bit and they really are good. I’m actually using tumbleweed on a home server right now and it’s been a champ. But…
My biggest gripe is opensuse seems to use different package names than any of the other distros for basic packages. I had to install a package that used capitals in the package name, and coming from mostly debian based distros, that made me rationally angry when trying to find the package I needed. I think it was network-manager or something that’s usually installed by default and I wanted something familiar.
Online directions for setting something up usually has deb and/or fedora rpm directions, which is usually just some difference in package names and the equivalent install command, searching the base package will let you figure it out. I had very few issues following debian/Ubuntu directions and translating them for fedora. Opensuse is always non-existent so you always need to translate those directions for opensuse, which is usually like doing it for fedora until you run into point (1).
