Yeah, to be honest I think Ubuntu should've picked KDE. It's a more direct competitor to Windows 10 which is in my view the best desktop OS. Gnome 3 is nice, just had it installed a couple of days ago. But some things are unpolished, some don't make sense. GTK open dialogs don't even have proper image previews which has been a feature requests for a lot of years (something KDE does have).
