Pulp Fiction Heroes Vs Superheroes

Whats the difference between a Pulp Fiction Hero & a Superhero? Do they just consist of Street Levelers when compared to Superpowered characters?
And also Who do you think is the best Pulp Fiction Hero? IMO Its either The Shadow or Phantom

@deadgod: Nothing. There is no difference between a Pulp Hero or a Superhero.

It's like OJ. One has pulp, the other doesn't.
