I'm also addicted to the hot corner overview and keep ramming the mouse into the top left corner also in desktop environments without that feature - it's addictive! Cinnamon has hot corner functionality as well but only Gnome Shell has the unified all-in-one-place overview.
Gnome Shell is quite popular, just not 'round these parts so much
