Re: I'll stick with my MATE
"I find that I do not miss 3D desktop effects one little bit; most of what I do involves what is in each window, be it Firefox, a terminal or whatever and I use the window manager to, well, manage these windows and manage the virtual desktops. Gnome Metacity Flashback does this perfectly. It works, works well and does so consuming minimal resources."
This is what I find as well (Lubuntu user) and have struggled to find:
(a) reviews that compare / describe useful functions of other DEs; or
(b) any description of why 3D / compositing / transparency / whatever is actually useful.
This is a genuine question - any answers to (b) above gratefully received.
