Animation quality notwithstanding; it's rather obv than Avengers: Earth's Mightiest Heroes pales in comparison to this one. Once and if you're willing to gave it a more objective look, of course. For instance, I didn't like how they handle the Wonder Man or Vision characters in the newer series. And I didn't mind the perceived lack of appearance of the major others in this one. As a matter of fact; I wouldn't have noticed if not explicitly pointed out later on. And in a way, I'm glad that they didn't appear. They're boring, overpowered and overrated egotripping asses anyhow. In particular the Hulk; he can go smash himself in the head all he wants, and make himself even more dumber, for all I care. He even comes more unlikable and unbearable that Hawkeye; in any incarnation. I also felt that the older one was closer to the comics; albeit the West Coast branch; and had more originality and distinct personality on itself. Also, I thought it was a clever spin of the same old; and at least a way above average offering. It was also way more interesting, since it was set in a slightly alternate future. The explanation for their powers made even more sense here than in the comics, and was more than adequate; even the secondary ones. They feel more like a real team too. It's a pity that it was so abruptly cancelled; and didn't get a decent run. It'd been nice to see it further developed; since the story and plot were really good. Eg, I'm certain they'd make more use of the suits; but sadly never got the chance. Even the arcs were more freshly engaging that AEMH too. Animation was not bad; but it wasn't great either. It was good for the time, though. And it's still decent to this day; IMHO. So all-in-all, I don't understand how some people can call themselves true (hardcore) fans, and not like this (WTF?!) Simply because it didn't fit in their little minds' preconceived ideas of what it supposedly should've been. Jack Kirby and Stan Lee were credited as writers and creators. Even Stan Lee and Avi Arad were further involved, and are listed as executive producers, for gawd sakes! What else does it take for menial dogmatic stubborn pompous asses to just get it?! And I don't understand their toy line argument either; since every media franchise, since I have memory, has attempted to further capitalize in that way. In any case, I remember this airing during the 90s; which was when I first saw it. So to me this will always be the definitive and original (animated) Avengers! A step forward in the whole Avengers universe anyhow ever since (a kid's series' better than none:) Anyway; lots of action, and although obv geared for little kids; it also equally offers lots of twists and drama for adults. So do yourself a favor and watch this underrated gem, but with an open mind.:)
