I actually don't mind the GNOME metaphor... but they make it less and less usable over each release. Philosophically, what they are talking about sounds great, but pragmatically the system is just getting less and less usable. UX consistency is good, but not when it comes at the expense of functionality. Also, I don't like that GNOME has been ideologically captured by the extreme left.
Back in the day I ran WindowMaker and FVWM, but nowadays, with Wayland, HiDPI screens and expectations of integration, it is not a viable strategy anymore.
