TWO ICONIC characters in capes first rocketed the comic-book industry into the American mainstream: Superman and Batman, twin pop-culture monuments who, though born in the late ’30s, still reign ageless. And this coming Friday, these live-action Spandex heavyweights will go (Super-)mano a (Bat-)mano for the first time on the big screen, in director Zack Snyder’s “Batman v Superman: Dawn of Justice.” So who has the edge in this epic showdown of DC Comics’s most popular warriors? Sure, Superman is the stronger combatant — but don’t think Batman doesn’t have something in his utility belt to counter him. For each category, tell us which one you think has the advantage, and then we’ll tell you our take.
