Fleischer:The animation is beautiful. Still the most quintessential portrayal of Superman in animation.
Adventures of Superman:I like the style/tone of the black and white era. George Reeves is a great Superman.
Superfriends:This is probably the only Justice League related media where it feels like Superman actually IS the leader and "greatest" member of the team. Often in JL media, it seems like they're only paying lip service to that concept.
Donner:Best live action portrayal of Superman and easily the best live action portrayal of the Superman/Clark duality. Stamp is still the best Zod in any medium.
Lois & Clark:Teri Hatcher as Lois Lane.
Superman: The Animated Series-Any episode that involves Darkseid/Fourth World, "The Late Mr. Kent", and the mxy episode.
Smallville:Lionel Luther.
Justice League/Justice League Unlimited:Superman's fights against Darkseid, Mongul, Captain Marvel, and Captain Atom. The episodes "Twilight", "Hereafter", and "For the Man Who Has Everything".
Superman Returns:Superman saving the airplane.
DCEU: The Smallville battle in "MOS".
Arrowverse: Brandon Routh returning as Superman.
