In 1996, two cartoons came out that had a lot in common. One was about an average, plain kid and his best friend, who interact with the city, their families, and their eclectic elementary school class, as they learn important life lessons. That being Nickelodeon's Hey Arnold! The other show revolved around an average, plain kid and his best friend, who interact with the city, their families, and their eclectic elementary school class, as they learn important life lessons. Arthur from PBS. Despite a near identical premise and concept, the two are very different in terms of execution and setting. The question now is, which executed it better in your opinion? I myself, am torn, as I've only just began rewatching both series, and they still hold up.
