[DC] Why does Luthor harbor such a hatred for Superman yet not "other" godlike beings?

We've seen Luthor sometimes form alliances with other alien beings, or other superhumans, why does Luthor not share the same hatred for them as Superman? Is it something personal? I mean my understanding was that Luthor is arrogant and envious that he gets to be a human yet live in a world with all these other super beings. So why doesn't he get mad at Shazam, or Wonder Woman or anyone else who is also in the leagues of Superman.

Why Clark Kent?

Well for one, Superman lives in the same city - and thus is a perpetual thorn in his side. 

Another reason is that Superman is an "imposter," an alien from another world galavanting around with his superpowers but who looks just like you and me; Wonder Woman is an Amazon, she's okay because they're from Earth. Same with Flash, just a human but with superpowers. Lex projects his ego onto Superman, and it makes him feel insecure to be this weak, helpless human standing next to a Kryptonian who *obviously* thinks he's better than actual humans, because that's how Lex would feel in Superman's shoes.

Martian Manhunter, Darkseid, and other aliens at least look different enough. They're just freaks from other worlds, as far as Lex is concerned. But Superman... Superman is better at being a human than other humans! He makes real humans look bad!
