Oh man, you haven't seen Akira yet? What are you waiting for? Just be sure to get the DVD version. They did an excellent job re-dubbing it and getting the original print cleaned up digitally. Then, if it interests/confuses you, check out the full 6-part manga series just released a couple of years ago. The movie barely scratches the surface of the original story. They are both excellent.
I never really watched Robotech. I have seen one of the newer Macross Plus movies, and it was pretty wild. I enjoyed "Ghost in the Shell," though it was a lot more metaphysical than I had anticipated. "Dragonball Z" has been one of my guilty pleasures since college, but I haven't seen it in a long time, although it really started to go downhill towards the end.
If you haven't seen "Cowboy Bebop" yet, then also do yourself that favor. It's a 24-episode series (with one recently-released movie, too) that is just superb. "Akira," while very good, has somewhat dated animation, but "Cowboy Bebop" is top-notch, and the English dub is actually, in my opinion, far superior to the original Japanese.
FWIW, the Australian DVD of Akira contains BOTH studios' English dub soundtracks.
Australia tries to throw a little something extra to the market since they are generally last to release a title.
