Who Is Faster: Flash or Superman?

The Flash (Bartholomew Henry Allen) is a fictional superhero who appears in comics published by DC Comics. His power consists mainly of superhuman speed. Various other effects are also attributed to his ability to control the speed of molecular vibrations, including his ability to vibrate at speed to pass through objects. The Flash wears a distinct red and gold costume treated to resist friction and wind resistance, traditionally storing the costume compressed inside a ring. [source]
