I've used KDE for the past year, and it's just too much, too many options, and if you stray out of the happy path, you encounter plenty of bugs. Then what's the point of offering so many options. I'm back to GNOME.
KDE enjoys a lot of reputation from people that believe the Windows-style UI paradigm to be the best. That's arguable. I would certainly install KDE to a user new to Linux, but I have been running Linux long enough not to get lost if I don't have a taskbar or desktop icons.
GNOME could be so much better, sure, but I prefer 2 options that work (4 code paths to test), than 10 that don't really work all that well (1024 code paths to test).
My dream DE has the simplicity and design of GNOME with the completeness of QT. GTK is a dead-end, but at least it's written in C, so it is future-proof compatible with better languages such as Rust, instead of being stuck with C++ until the heat death of the universe.
