As much as I love both characters (I go back and forth as to which one's my favourite), I would much rather be Batman. As haunted and psychologically unstable as he is, Bruce Wayne has the satisfaction of having built Batman from the ground up. All of his skills, all of his strength, all of his knowledge, is nothing but his own. Striking fear into the hearts of criminals - having felons flee from you - being the Dark Prince of the Night, how can you beat that? Superman, to put it in crude terms, won the genetic lottery......
What's wrong with the genetic lottery?
