Pros
Pro Simplicity of Gnome with the power of Ubuntu
Debian was good to use but has limited documentation and is difficult to pick up. Ubuntu MATE brings the ease of design and logic of the Gnome 2 style desktop so it's easy to get around coupled with the vast documentation, forums and ease of learning/using the Ubuntu system.
Pro Perfect for people who like Gnome 2
The goal of MATE is to maintain the look and feel of Gnome 2, while maintaining compatibility with Gnome 3. To that end, it has also forked and renamed many of Gnome's core applications. It benefits from the years of work and polish that have gone into the Gnome project.
Pro Easy to understand for beginners
MATE is a desktop environment that is simple enough, making it easy for new users to grasp the interface.
Pro Welcoming community
The community is always there to help you. And listen to your feedback.
