Frank Miller did an interesting comparison as far as 'humans among gods'. Daredevil is *human*. He does have superdetection powers and supertraining and I'm pretty damn sure he has some kind of ninja meditation superhealing, but when he fights Namor or the Wrecker or Hulk Daredevil realizes pretty quick that he's out of his league--at that point he gets his ass beat. The few times he's beat someone out of his league (Klaw, Ultron), it's because they had a specific weakness.
When Daredevil goes up against Captain America he notes how superhumanly better Cap's body is. How lightning fast Cap's superhuman mind works strategically, altering his actions and plans on the fly, giving the impression that 'the script is with him'. If you had to compare him to someone physically, Deathstroke is closer than Batman.
