The reason I don't use Gnome is because it's only usable after you've installed a bunch of extensions yet after every update, half the extensions are always broken.
I don't understand how you could say it's like Windows 8? I don't really see any meaningful similarities. Gnome is very much just its own thing.
It's the other DEs that are like windows. Start button bottom left that opens a cramped app menu. Taskbar on bottom. Clock on bottom right. Minimise, maximise, close buttons on the top right of each program. The Win95 UX paradigm, basically.
I don't like desktop GUIs that aren't designed for a mouse and make you memorize keyboard shortcuts to be usable. Keyboard shortcuts are nice to have but shouldn't be mandatory, IMO.
