You're totally off-base.
Doomsday haunted Superman for a short while, yes, but Luthor has done more damage in his career to Superman and Superman's life than Doomsday could ever hope to.
Luthor is Superman's ultimate challenge because he's the part of humanity, that very thing that Superman loves, that Superman can't save. Superman did have nightmares about Doomsday, yes, but only for a very short time. Luthor gets inside Superman's head and makes him react in ways that nobody else can. Superman lies awake at night worrying about whether Luthor will ruin his life in the morning, why? Because Superman can't beat Luthor by just punching him in the face.
Joker is the same to Batman.
