Agreed about the George Reeves' version ... I *loved* to watch it on reruns growing up!
Christopher Reeve got me officially hooked on Superman as a kid - but it wasn't long after that I started watching EVERYTHING I could that related to Superman. Even started with the comic books, though I never followed them religiously. But as for TV and films, that included The Adventures of Superman, the cartoons, all four Reeve films, L&C, Smallville ... only thing I skipped was the Superboy series.
