I got KDE going on the Pi a while back but there were a bunch of problems. Biggest was I couldn't right click plasma widgets. Still, Kubuntu would be great. I'm an Android guy too and KDE Connect is simply the best interoperability tool available, IMHO.
EDIT: And now that I think back on it the reason I gave up on my KDE4Pi2 project was because I found a bug report for the right click problem that had been open for something like a year (maybe it was several months) and I'm just not that patient of a person. That was ARMHF though and I see they're more into the mobile side of things now, so maybe the situation has improved.
