the way Thor generally approaches a fight like this, he loses. Thor is a peer to Superman, but she's as strong or stronger than Supes, meaning she's at least as strong as Thor, and likely stronger. She has a durability edge and a speed edge...and she's a woman. While Herc is more of a chauvanist than Thor, the thunderer rarely seems to really go all out in beating women, and ANY hesitation in a fight of this calibur could well mean defeat. While I believe Thor to be overall more powerful, and certainly capable of winning such a confrontation, I think that initial hesitation and her tend to not hold back at all means defeat for the Thunderer.
ffs they made this pretty clear.
