I've tried several KDE distros over the years and they have all been quite easy and pleasant to use, despite the occasional crash. There was nothing particularly bad about the UX. The reason it has not been successful is of course the largest Linux companies choosing deliberately to back GNOME. The initial reasons may have been legal but they stuck with GNOME despite the latter removing features during 2 to 3 transition and despite the legal situation resolving and KDE becoming better and better over the years. Corporate steering of s/w is very real though most seem to tiptoe around the matter...
