Ubuntu MATE is a stable, easy-to-use operating system with a configurable desktop environment. Ideal for those who want the most out of their computers and prefer a traditional desktop metaphor. With modest hardware requirements, it is suitable for modern desktops and laptops, micro computers and older hardware alike.

Pros
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 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.
Cons
Con Bugs in Slovenian and Portuguese versions
Looks like there is an anoying bug for Portuguese and Slovenian users that has persisted from the 20.04 version.
