People are saying Escanor won because of his peak of power and all the energy he stored up over the years was the cause, and therefor he's the strongest of the sins
But other people say Meliodas is stronger since he only took 78% damage compared to Escanor who has taken much more damage, and he only took 78% because Escanor used up too much magical energy defeating Meliodas.
So who's stronger, and did Escanor really win the fight...?
