In short, yes. It uses a shell over regular old GNOME 3.
If you wanted a version of Ubuntu that isn't fucking TERRIBLE, Install Linux Mint Cinnamon. Its user interface should be very familiar to anyone who has ever used Windows. Its Desktop Environment, Cinnamon, is based on a fork GNOME 3, which was created directly in response to GNOME 3 being fucking garbage. It takes all of the good parts of GNOME 3 (which were mostly holdovers of GNOME 2 anyway), and puts it into a much sleeker, better put together, package. The CoC has no purview over it. I personally use this, and without powerleveling, as I have really nothing personal on this system, I can show you my desktop:

The best part of Cinnamon is its personalization. You can change absolutely fucking everything about it with complete ease.
If you wanted, you could also install Linux Mint Mate, which is based on a fork of GNOME 2, and actually good piece of software that was made before GNOME became a tranny. It's about as good as Cinnamon, but the layout isn't quite as personalization-friendly, in my experience. The problem with Mate is that you may find it becomes outdated quicker than Cinnamon will, but the devs on the project are doing an excellent job, and it's made up of a team of the people who founded GNOME, and made it viable, versus the HR department that GNOME is now.
