Wasn't Bor weak when fighting Thor?
And Thor was the Serpent's Kryptonite.
So their low showings were circumstantial.
My conclusion.
Bor was a founder doesn't necessarily means he is an uber All-Father.
Serpent is as strong as the fear he harnesses. With enough fear he would've eventually been unstoppable. Odin knew this and wisely took no chances. Though he should have had more balls and attacked him instantly after his resurrection.
I see the true All-father and rightful heir to the throne winning this if his final power level is his limit in this fight.

Yes he is . Also , for whatever its worth , Fraction retconned the circumstances surrounding Bor's death , by doing this :
Fraction seems to suggest that the Asgardians are unique in that all their "stories" are right and canon due to various cycles of Ragnarok and the nature of gods and stories being able to be re-written.
An ambitious take, but best suited for someone like Ellis or Morrison or Hickman.
