I use Ubuntu daily, so I ended up stepping onto this land mine. Overall, I don't think Gnome is completely unusable, but some little things made me jump back to Unity (which can be chosen when logging in).
Gnome is very customizable, is more attractive looking on Ubuntu 17.10 out of the box, has better notifications, and doesn't generate the questionable error messages that Unity does.
That being said, it feels like replacing a Toyota with a Buick.
Damn, I love javascript on the desktop.
