I originally quit Ubuntu because I didn't like Unity ... Gnome is great, I can live with KDE but now I'm moving towards even lighter solutions. I won't miss Unity at all!
Gnome3 won't be a good move from Plasma5.

Doesn't do as much, granted, but isn't that kinda the point?
It's also a bit more of a pain to run multiple monitors with RatPoison and I've become well acquainted with reorganizing my screen configurations using the console commands to xrandr.
I also should have noted that I switched back to Xubuntu from Linux Mint.
