JoJo no Kimyou na Bouken (TV)

Gentle and lazy blue haired protagonist and his legacy fighting a charismatic fabulous blond stud with cosmic ambition and looser morals through battle of wits in a sprawling epic where nobody is plot armored.
LotGH is far more serious, realistic, politically and militarily centred, science fiction/space opera, the perfect seinen, while JoJo is well bizarre, very creative in its setting, supernatural with super powers, the perfect shounen.
Good old retro titles, seminal masterpieces, influencing the entire medium, and getting a re-adaptation nowadays!
Bonus: both strongly influenced Death Note.
