Anyway, to get back to on topic, I wouldnt go so far as to give BA the win; this version of Thor was very dangerous...
Yes, he could be overly aggressive at times and error as a result (like how he errored against Bill), but he had several fights during Blood and Thunder where he was hyper agressive and didnt error (like when he defeated the Infinity Watch and when he soloed Surfer and Warlock together)...
I think Blood and Thunder Thor kills BA here more often than not...
Black Adam could get a few wins if Thor errors, but thats only if Thor errors (its not a given)...
Blood and Thunder Thor...7/10.
