I rank it this way:
Sunbow (excellent voice acting, animation, characterization, and story direction)

Sigma 6 (serviceable in some aspects, but silly anime cliches always brought it down, voice acting was inconsistent at best, horrible at its worst)

DIC (Do it cheap. Bad voice acting, bad animation, nonexistent characterization, boring stories)

Frankly, I think the DIC Joe cartoon is horrible. I saw some of the clips on you tube recently. It rubs me the wrong way, seeing it for the first time in along time.
