An average kryptonian brain on krypton already has genius level intellect, with the super speed and everything that he gains on earth...I would say superman is smarter than batman in some instances but not tactical or strategical knowledge
Then why's he dumber than Lex Luthor if Superman is already a genius?
Lex Luthor always outwits Superman every dang time. Like how he built a giant generator under a city and Superman thought it was a bomb so he went and destroyed it. And then Lex Luthor got all the people on Earth to turn on Superman because he made it seem like superhumans are a threat to humanity after they discovered the generator wasn't even a bomb to begin with.
