@vickysteeves One more Mate vote here
Sorry to disappointed you, but I actually like Gnome. My second choice is Mate (for older PCs).
@vickysteeves Whar was wrong with KDE? It seems to be faster than most and you can modify almost everything to fit your work flow?
Have you tried mate?
@vickysteeves I use both Cinnamon and Pantheon because I use Mint and elementary every day
