For me its Akira's Streamline dub. I dont care if the Japanese biker gang sounds like there from New York I love it and for me its A-kir-ra not Ak-ira.
"Clash of the Bionoids" dub of Macross: Do You Remember Love was always a special dub. Dubbed in Hong Kong with British/Australian voice actors it was originally used (with Japanese subtitles) for education purposes.
Don't forget the old VHS Dub of the Gundam movie trilogy
Steve Blum as Char was surprisingly good lol, though the rest was awful
Also, and probably less well known, ADV did a legit dub of Macross (not Robotech, the actual Macross). Mari Iijima even reprised her role as Minmei for the dub.
