Answer:
I would say they are pretty much equal.
They both are super powerful, have perfect control of there powers, great at wielding weapons.
Percy would be better in a sword fight, fighting Titans, and Gods & Giants. He tends to break the rules, and get in a lot of trouble as well as being to loyal for his own good.
Jason, would be better at control, leadership, he is super honorary, and never breaks rules.
It would be a super hard choice between the two. The are pretty much are equal on a scale.
