Neither are very realistic, but Batman is technically
quite a bit more on the realism side than Superman. Definitely not saying I prefer Bats or
Supes, nor that I have favoritism for either hero, i'm just stating my opinion on such.
That being said, I can of course see how everyone should know that the villians for both are a good representation of how strong they are at any given point in their respective histories.
Wouldn't be much of actual "villians" in either of the heroes' story if they got rekted just as easily as they were written up and put into a story to go up against either hero in their comics/shows, no?
