Durability goes to Eric Bana.. He easily handled a 22 gigawatt powered David in the clouds for 17 seconds and it did nothing.. Regular lightning(1.2 gigawatts) is 30,000K.. Meanwhile Thor couldn't survive 50,000K of uru metal melting point.. This is no diff at best, if Hulk decides to hold back and let Thor attack him.. Stormbreaker won't do anything considering uru psi is 1037 tons while Hulk's base skin is 2625 ton psi in tensile strength
