<<Answer me leo!!>>
hahahah! easy, easy - i can only respond to 6 threads at the same time! would a godblast end supes? depends on the blast. seriously. thor has blasted with his hammer many times and the damage had not been that great. a FULL UNFETTERED god blast? yes, even if it didn't ko him directly (which it likely would) it would weaken him enough to the point where it would be an easy mop up. if it hit. the full force requires a bit of time to summon, AND thor would have to be able to have space to issue it. if they were in close combat i'm not sure he could use it effectively. that's why i don't see the attack being a serious option for thor in this fight. name a speedster he's ever hit with it.
if the fight gets in close, (which it surely wouldm given the nature of the 2) it's a war, but i think supes (with his speed, str and durability adv - imho) could withstand the hammer and thor as often as not.
IF a godblast somehow hit (not sure the circumstances that could happen under though - maybe if thor REALLY scored a good shot then before supes recovered he could hit him with it) thor wins. i don't see that happening often, and in close, h2h i still say it's too close to call.
