SS catches Thor's best blow with Mjolnir (after a sucker strike from it). The best Thor could do was dent SS head, which is completely healed on the next page. Notice SS takes no visible damage from a direct blow from Mjolnir whereas Thor bleeds from a single strike from SS's board.
Also notice Thor's enraged, bloody face vs SS demonstrates his usual calm, negotiative demeanor.
Here we see that bloodlusted Thor = or arguably < a very restrained, subdued SS (typical of both character dispositions)
In this scenario, he has the home turf advantage because the fight happens aboard the Millennium Falcon. I'm sure Han has it rigged with trap doors and booby-traps that he could use to his advantage. Han's blaster MVP (I'm assuming that Indy has his pistol and plenty of ammo).
HTH, though, Indiana Jones has been shown to tank much more punishment, giving him the edge.
