In your opinion, what are the pain points of KDE?

For me, my biggest beef with Unity was a death from a thousand papercuts. EG: i wanted to open a file in a program and had to navigate to the location, and couldn't just copy the folder path as I did on Windows. Or when I wanted to Alt-Tab between two windows of the same program, I couldn't do it with Alt-Tab. To remove it, the forums told me to launch a program which then for some reason didn't open when I double clicked on it. And then I realized that Sublime Text was not longer called Sublime Text but Ubuntu somehow renamed it to the last file opened as admin, which was aparently a well known bug with Unity.

Then I read that the next version of Unity is a rewrite from scratch, with usually means many new fun bugs, and just said 'forget it'.

Now, is any of these DE simple to use and with well-thought defaults? I can try out a few ones (after all I will do a clean wipe of my desktop) but sadly don't have the time to test more than a few DEs.

I think KDE, MATE, Xfce and Cinnamon have all (mostly) sane defaults, and are simple enough to use, so it's mostly a matter of personal preference. I'd choose KDE though - I have used Xfce for years before, and it always felt somewhat limited.
