Using Ubuntu Mate as unified interface

I am working on Jetson Nano AMD64 (18.04) and Intel based Linux machines. The Nano is rather stuck on 18.04 at the moment... I tend to run the Intel based systems on 20.04 base Ubuntu desktops are exactly the same except where its different. I have been looking at Mate as a possible unified desktop for the two versions...

I would appreciate the communities thoughts on any gotchas or issues that might occur is following this path.... or any other suggestions

Many thanks for your time
