Never tried to watch Extreme.

Dic's voices and writing were fairly awful.

Sgt. Savage's one shot was kinda crappy, but at least tied into ARAH (Gen. Blitz helped create Cobra...figure that one out...)

Sigma Six had the animation (when characters were actually moving) but the plotting was repetative, the characterizations mostly flat, and stories glacial.

Sunbow was spotty, but they had better writers and better voice actors. I think the Movie left a bad taste that never went away. Also, people fail to understand that it was totally impossible for an American produced children's cartoon to show the level of violence the GI JOE comic book was allowed. In fact, it's surprising Hama was given as much leeway as he was, probably because the comic book was just a stop gap until Hasbro could legally make an animated show. And that parents didn't read their kids' comics, but did pay attention to what they watched.
