Counterpoint: GNOME and the modern GTK framework
(I needn't say more.)
(I needn't say more.)
I suppose I should say I found Gnomes luridly chunky decorations and widgets to be personally offensive.
Among a great number of things I really like, I will mention that Caja, the MATE version of GNOME 2's Nautilus file manager, can still be switched to spatial mode.

Generally speaking, I too really liked GNOME 2.32 and its predecessors, and, as far as I'm concerned, MATE is as it describes itself.
EDIT: Wording mistake.
GNOME offering a monolithic environment with heavy opinionation is the opposite.
