Now this is exactly the problem addressed in this blog. You are obviously a Spider-Man fan and underrate Batman. Symbiotes have known weaknesses, which would make them rather easy to beat for a gadget-user like batman. A simple flashbang grenade is all it would take. With the right knowledge and planning a regular SWAT team could beat them. And Batman is a world class hero, comparable to Captain America in experience and tactical skills.

I agree that he would be hard pressed to beat Spider-Man, who has no such obvious weaknesses (if he could do it at all). I tend to put more credit to experience (rather than powers) than most people.
