I don't think location would matter much at all... Mostly because of DD's radar sense, but Cap and Elektra are both plenty good at sensing incoming attacks and such.
Team Bats is simply outskilled. I'd give Batman a very thin majority over Cap, if only because his gadgets are much more useful aginst other street levelers than the shield. (on the other side of the coin, Cap's shield remains useful for anyone into herald levels)
Besides Cap and Batman, Daredevil and Elektra VERY clearly outclass Tim Drake and Dick Grayson. I'm not disrespecting them, but Nightwing gets by on having good agility. Daredevil's agility is arguably better, and his enhanced senses basically give him a form of precog. Whatever Nightwing can do, Daredevil can do better. Tim Drake is cool, but he's still a kid... In a fight, he can't stand up to Batman. He's simply not as physically good, nor is he quite as skilled. He's good, yes, but Batman is clearly better. Similarly, Elektra outclasses him in everything but sleuthing. Awesome as he is, Tim's getting beaten up.
Basically, Tim and Dick get murdered, Bruce gets triple teamed. I don't see many points going to the Batman side here at all.
