i agree. the storm, even if its uber, would pass and you could repair your stronger buildings. however a vortex is guaranteed to destroy everything directly in its path and heavily damage anything near. however, if the storm was as powerful as a thor and moved very slowly theres really no difference between the storm and a vortex, only that the animation is different. the result would still be the same and in such a case i would question the purpose of having two types of disasters that carve the same path of destruction.
