It's visually cluttered, the title bar is often missing an actual title, every control on there takes longer to respond to a click because it has to wait to see if you want to move the window instead, the menu takes an extra click to open and is also really slow, the menu doesn't include keyboard shortcuts ... The applications which have been converted are much harder to use. For example, I found dconf-editor in particular is now extremely frustrating to use, since it doesn't have a treeview - it's impossible to explore more than one recursive path simultaneously, and the mouse distance between opening a folder to see its contents and going back to its parent is now quite large. The title bar doesn't have enough space to display a long path due to it having lots of other controls in there, and ends up showing something like '/ com / ubuntu / Ab...xy / ap...ons / ap...ons', or worse, only the most nested folder name. It's also just really ugly: cluttered, busy. The good thing is there are no - zero - gtk3 apps that I need to use.
