In general I really dig ubuntu 18.04 and gnome but with my home setup being a mix between a 1440p monitor and a 4k one, unity/16.04 is a pretty clear step ahead with the out of the box ability to scale OS UI elements differently on each display as well as do fractional scaling. Only missing link is window contents still have to conform on both monitors to one of those scale factors. Irksome but passable. Will stick with this for now
