Now this can be quite the fight if one considers how much power both gods of wrath have in their arsenal. while asura may appear to be miles ahead in physical strength compared to kratos, do remember that kratos himself possesses a lot of things if everyone remembers what stuff kratos has acquired throughout his travels, most notably From Gof of war 2, the power to change fate itself after he took out the sisters of fate. Of course if kratos was smart enough to know that he can literally change fate as of god of war 2's events, he shouldnt have trouble against beings of gargantuan strength.
Then again asura is kinda smarter than kratos.
