It depends entirely on what you personally like and what exactly you consider a base. I think something like a leopard really "enhances" the look of a lesser. Does that make leopard an enhancer? Most people would probably argue no but in that situation to me it is. On the other side OD is commonly considered an enhancer but I don't think it enhances Mojave, I like normal Mojaves significantly more. Does that mean everyone will fell that way? Nope... it's all about your opinion.
