A quick internet search suggests that most/all Super Cs are diesel powered, and Jayco, Dynamax, and Thor versions all suggest they have "full body paint" options. So they have a better chance of not looking ragged after a few years of use. They will always look like a class C motorhome if that's not what you're looking for.
I have no idea on which ones are good/bad.
