I've just uninstalled openSUSE Tumbleweed after using it as my primary dev machine OS for about three months. One good thing that can be said about it is that it has the most stable KDE packages of all KDE distros that are still left. Other than that, it was the most unstable non-Microsoft OS I've ever used. Kept crashing on me all the time, updates broke stuff frequently. After the last update, it refused mounting my encrypted home partition for whatever reason. From my experience, I'd recommend steering way clear of openSUSE if getting actual work done is a priority.
