That period I stopped recommending linux to friends as I felt burned by the experience of losing gnome 2. I remember going from ubuntu 10.04 beyond support, to xfce, gnome fallback, gnome flashback, linux mint cinnamon, crunchbang (stayed a while), linux mint mate then ubuntuMate, where I've been for several years now.

I'd say UbuntuMATE is functional, boring and pretty, and frankly should be the modern standard for a work environment linux.
