One of the things that Macross has, that Robotech doesn't, is the sense-- at least for me-- of something bigger is behind it all. I don't mean Protoculture or the ProtoDevlin, or even the missing Megaroad01. I'm just talking about each of the series having a sense of being just one tiny little story in this massive universe, and that humanity is moving towards something that is just going to blow everything away. It's the little bits and clues and bread crumps left from show to show, where just when you think you've got it nailed, how the Macross Universe works, you realize you're wrong.
It isn't just all gutted and spilled out on the table like Robotech. There isn't an compulsive need to make everything inter connect to the point of making the universe seem about as big as somebodies backyard.
