Sure I watched Astro Boy, Speed Racer and Starblazers (Yamato) as a kid in the 70s, but it was really Macross/Robotech/Dyrl in '85 that really introduced me to anime. I think there are plenty of other great anime titles like Akira, Cowboy Bebop, Trigun, Evangelion and so on. However none of them had the influence on my life like Macross had and so, to me, none of them will ever compare to Macross.
I can certainly tell you that a lot of my friends feel the same way.
