No! According to me it’s a new thing to many working with it, and there are still hardware compatibility and all kinds of other issues needing workarounds and so on.
I was also saying that way too many people try another distro because of a problem on the one they are running, only to get whatever is wrong with the one they switch to. I learned how to be patient, and help out where I can with bug reports and suggestions.
FYI: I tried XFCE, and it’s nowhere near as capable as Plasma, and plasma has a much larger code base too. Your analogy of “Well it all works on XFCE” is a logical fallacy, because there’s a lot of stuff that XFCE can’t do that Plasma can. When I was on XFCE their developers were slow to make changes, and were unwilling to add great features, and that with bad excuses (much like the Gnome folk), that has never happened to me with KDE! You are comparing an aircraft carrier to a fishing boat!
As a power user XFCE has nothing for me, and a little bug here and there is nowhere near a good enough reason to switch DE’s, only to have to deal with everything that’s wrong with it.
