Ubuntu GNOME is an official Ubuntu flavor featuring the GNOME desktop. We aim to provide a relatively pure GNOME desktop on top of the popular Ubuntu foundation. We believe the combination of Ubuntu and GNOME is the best choice for those looking for a beautiful, simple, and usable operating system.

Pros
Pro Offers a pure Gnome desktop experience
The Gnome desktop environment included in this distribution is untouched, offering a pure Gnome desktop experience. In addition, all the important Gnome apps are already installed, such as Nautilus file manager, Evince document viewer, Evolution personal information management application, Gedit text editor, Cheese webcam software, Empathy multi-protocol instant messenger, and many others.
Cons
Con Relatively high system requirements
The Gnome desktop environment is a resource hog which requires hardware accelerated graphics rendering in order to run smoothly, making out of the box Ubuntu Gnome unsuitable for low end systems and older hardware. Even mildly aged hardware, you'll get far better performance out of a lighter desktop environment like LXDE or XFCE.
