I like Robotech, because I watched that as a kid, 18 years ago. I discovered Macross a few years ago, with internet. I have a few toys from Yamato because they are good quality.
Actually, I love the macross TV series toys because indeed they are the same looking toys than the Robotech series but with Yamato quality.
I like Robotech also because they speak english and I don't have to read subs.
I didn't like DYRL really. I don't even understand the story very well while the Robotech history is clear. I have the Robotech DVDs and not the macross ones. I believe they released remastered ones but they're damned expensive and still in japanese with english subs.
I liked Macross Zero, Macross 7 (also a little too "Magical" with Spiritia if u see what I mean), I also liked Macross + and Macross II. But the one I prefered were Robotech Macross Saga, Robotech New Generation (Mospeada). I don't know why, probably because of the english language.
