Linux Mint MATE - while it looks different out of the box - can be configured to look like Gnome 2 era Ubuntu by getting rid of the Mint menu and fiddling with the panels. It's probably not a good idea to mix the Olivia repo with the Saucy dev repos but you could give it a go.
I'm thinking that we should perhaps close this thread if I/we don't hear back sometime soon.
People get confused about release numbers/designations so we can't even be sure what version is actually being used, and people also need to know about the decreased support cycle for interim releases
Those who hate change should absolutely settle into the current LTS
