XFCE was my main desktop for a long time, it's what I'd go back to if Cinnamon ever stopped been the one I use everywhere - Cinnamon in many ways feels like what XFCE would have been if it was started decades later - it also (like XFCE) doesn't screw with the standard desktop UX approach and that's a must for me, 28 years of using basically the same approach makes me feel uncomfortable on anything else.
