Based on the question I'd have to go with Batman, if you fallen off a building Spidey probably has the edge but Bats ain't far behind but if your kidnapped or something then Bats all the way.
Spiderman is cool and highly intelligent depending on which version we're talking about but spiderman still is limited on resources..
Batman on the other hand.. super genius creeper detective that knows more about you then you do will probably be able to track you down before you even know your missing.
