Ubuntu is a swiss army knife with huge repositories and pretty neat user interface. But in my opinion it's a victim of its own success.
On the other hand Fedora used to be less polished but had decent quality software and was always on the bleeding edge of new software.
Things changed with Fedora 30. Both server and workstation work smooth. Workstation is very polished and integrates well in the AD network. For the daily development tasks it is the best I had so far. Ironically I am developing .NET core applications on it using VS Code.
In conclusion Fedora has just regained its position as my main development system for a while.
