This. I was hanging on to Ubuntu 16.04 until a month ago just to keep Unity. After finally upgrading to 18.04, I spent a week on Gnome 3 and it was quite a frustrating experience.

Found Ubuntu Mate and am loving it! MATE Tweak gives you so many options to make the UI work like Unity, even better in some ways. The only thing I missed were application shortcuts, but now the fancy dock works just as well for me.
