Xfce is what I settled on, when still using GNU/Linux desktops.
I used a multitude of UNIX environments since 1994, starting with IBM X Windows terminals connected to DG/UX, and thanks to the way Unity got dropped, the way GNOME 3.0 went down, windowmaker no longer being actively developed, Xfce it was.
From where I am standing it feels more like bug fixing than anything else, like it was back in the 2000's, when I used to see what were the new WINGs coming out, and play around with GNUStep integration.
