This is a bit like, what contains the most heat.............Teaspoon of boiling water or a swimming pool?

I voted hurricane, purley on the basis that the energy that produces them is renewable and infinite. Bombs of any type have a finite amount of energy

If we are talking about a neutron bomb then it is a different ballgame. A neutron bomb could, in theory, burn off the entire atmospheric envelope in a single chain reaction. Which means there wouldn't be any more hurricanes
And a hurricane could blow up and destroy, said bomb before detination.
