Thundercats all the way. Why? Becasue the Thundercats storylines, for the most parts, continued from show to show and what was going in a few shows ago, affected future storylines. Great writing! Another aspect Thundercats excelled in way character development. The creators of He-Man and the writers did very little to give the characters an introduction or some type of clear background. It was like they just threw them into the show and some of the characters only appeared a couple of times and that was it. It wasn’t until She-Ra came out that the attention to details and storylines were put on the frontburner.
Thundercats, on the other hand had great character and storyline development, although, towards the end, I got tired of every other Tundercat turning into babies. What was that like 6 shows where one or more Thundercats were reduced to infancy?
Being that the Thundercats had great character development, you could not help but love the characters, villians included and you actually cared about what happened to them. In He-Man, I could care less about many of the characters partly because that connection was not established from early on in the series. He-man, Battle Cat, Skeletor, and maybe a few others were the only characters I ever cared about.
Overall, its an easy win. the Thundercats is a far superior show when compared to He-man in all aspects including background music and definitley audio. In He-Man, it was easy to hear that many of the voice actors were voicing many of the characters with little variation.
Also, the animation in the Thudercats was ten times better. In He-Man, they used the same cels way to often, but as a kid, I did not pay attention.
