I ran KDE for a year or so recently. The screen sharing bug, since I rely on screen sharing greatly for work, made me switch to something else. If that hadn't existed, I'd have probably stuck with it.
KDE is a great DE, but I've always found it more buggy than the rest. It also pushes the envelope, though, and really is a cutting edge DE.
GNOME might be more "stable", but I've also found you need to have at least a half dozen extensions and GNOME Tweaks to make it usable OOTB. Also, it uses as much RAM just doing nothing as a Windows install.
KDE has always been "Wow this is cool and very well designed" until I always run into a bug I can't get past and have to switch. This has been my cycle for half a decade or more:
- I hear about KDE's latest cool features (HDR support was the latest) and give it a try.
- I use it for several months.
- An update breaks something that is critical to my workflow and I have to switch to something else.
These days, though, I use Cinnamon. It is the definition of "just works" and other than network management GUI elements being kind of meh (especially for VLANs), I've found it to be rock solid.
It's "refreshing" to see conservative leaders in other countries are just as insane and inept as they are in the West.
