Budgie is an interesting UI. It is miles better than Gnome or Unity and more shiny than Cinnamon. I looked at the 15.11 release and it was very flaky but there was something about the UI that caught my attention. Looking at 16.06.1, it is definitely running better than the 15.11 release. It lacks the configurability of most DEs but it is young and will improve over time. It also seems to be less resource hungry than Gnome or KDE while at the same time keeping a modern feel. Definitely will continue to keep an eye on it.
