I'm fan of KDE universe. For me is the best desktop environment. I use it at home and at work, in a LAN against an Active Directory. However, along this years, I discovered that some features are broken and others many important for productivity remains unresolved for years. I'll put two examples. This is an unsolved problem since 2004 (https://bugs.kde.org/show_bug.cgi?id=75324) and today, 2019, is still not solved. so still is a headache for any Linux user to work everyday in a LAN easily, with flexibility and without issues.
A second example is something working perfectly that have been broken when Plasma arrived (https://bugs.kde.org/show_bug.cgi?id=351175). The issue is notified en 2015. Still the functionality is not fixed.
