I've been running Kubuntu 18.04 and so far I like it. It's customizable without plugins. It's closer to GNOME 2 than Unity was and GNOME 3 is. After installing the Nvidia drivers it pretty much just works. I wish there were more themes that were compatible across Qt 4/5 and GTK 2/3. The default theme, Breeze, isn't bad but it wastes whitespace.
