I loved the Shazam cartoons, as they were pretty much in the spirit of the old Fawcett stories, without being severely toned down, like the Super Friends.  it helped that the Marvel Family stories were never particularly violent and were more whimsical.  That translated well to a cartoon, with limitations on violence.

Hero High I liked in concept; but, the stories were never particularly memorable, the jokes were lame, and the voice work was nothing to write home about.  Filmation never had great voice directing; but, they had some performers who knew how to play stuff, like Ted Knight, Larry Storch and Jane Webb.  By this period, Ted Knight was a prime time tv star, Larry Storch wasn't doing as much and Jane Webb had mostly been phased out, with Tarzan, Lord of the Jungle as her last major series.   I was also in high school, and pretty much only watched a handful of adventure cartoons (Flash Gordon, Thundarr, Blackstar, Space Stars).  By 1982, I could drive and was working weekends at a restaurant, in the mall and Saturday morning was no longer a thing.  In college, I caught the Ruby Spears Superman and an episode or two of the Bakshi Mighty Mouse, as well as Super Powers Team:  Galactic Guardians, but that was it.  Sleep was more important.
