Query: Thor rivals Lee/Kirby's FF

Whenever the greatness of Lee/Kirby collaborations are discussed, their amazing Fantastic Four run is at the top of everyone's list. After finishing Essential Thor vol. 2 I think their Thor comics deserve a seat at that same Silver Age table of greatness. In this volume you get the debut of Hercules and his rivalry/friendship with the Son of Odin. Along with Hercules come the Greek gods and the villainous Pluto. Ego the Living Planet threatens the universe. In the back up stories, Tales of Asgard, we see the Warriors Three (Hogun, Fandral and Volstagg) join Thor at center stage to battle Fafnir the dragon, fend off Ragnorok and of course deal with Thor's evil brother, Loki. Highly recommended.
