Curiously my experience of Unity on Ubuntu 16.04 is the exact opposite. It's by far the fastest Linux desktop I have tried and I have been tinkering with Linux desktops since the early 2000s. My experience has been so dramatically different from some of the negative reviews I had read online that I can only conclude these are from older buggy versions or perhaps mis-configured or non accelerated GUI drivers.
For me it's been much faster and smoother than my 13 retina Macbook Pro and Window 7 Desktop and this on an ancient i3 2100 system with 4GB ram and old 6770 Radeon card.
My only regret is I didn't try it earlier because of all the negativity floating around about it. I suggest anyone interested in Linux desktops ignore the negativity and try Unity on Ubuntu 16.04 with an open mind. Its fast, lightweight and reasonably sleek and minimal.
This! The negativity regarding Unity is hurting Linux. So many people I know who tried a switch in the last couple of years were put off Linux because their Linux-friends pushed them to Mate or Xfce, running on Arch, or something similar. Those friends heavily warned against Unity and Ubuntu as if they were the devil. Showing those who were interested in a switch what a modern Linux desktop looks and feels like was a revelation to them.
