Another way I'd extoll the virtues of Steven Universe is that it's a show able to continue on with any number of self contained plots, limited only in possibility by the writers' creativity, for however long, giving it the ability to run as long as similarly structured shows like Adventure Time or FiM. But like those shows, there's a distinctly clear overreaching plot line developing, which will allow the makers to eventually wrap the story up neatly when they do run out of ideas.
Growing Around lacks any such greater continuity and like say, Spongebob or Family Guy (shows Enter hates), will depend on being funny enough to get by on fan/network goodwill and Random Access Humor, instead of having an internal plot to serve as the framework of the one-off episodes.
Which it lacks, of course.
