Elementary looks like a great attempt at a clean desktop. Lots of attention to detail (although odd that they have a gif searching applications on the front page with such a mis-centered text insertion mark!).
I really wish that Gnome would go all-in on the single menu bar approach of OSX. I know it's gone back and forth over the years and broken from time-to-time but it really is a much better way to do things versus the windows menu-per-window approach. IMO obviously, but I've used OSX for a decade and Windows/DOS for 20 years before that and top menus have always just been a better experience.
The menu bar is one of the most frustrating parts of macOS for me. It kills Fitts' law when navigating browser tabs, which is what I'm trying to do up there 90% of the time.
I think the trade off - benefitting from Fitts law when you need to use a menu AND saving screen estate - is worth it. At least switching tabs is a trivial keyboard shortcut.
