Except you're talking about fiction. Akainu's devil fruit is stated as a better version of Ace's, even though in real life fire can be way hotter than magma. Ace's fruit at least ties with Aokiji's, in favour of the mera mera fruit. => akainu's fruit is better when they are fighting 1 vs 1.

Also, stop trying to be a fucking smartass because you're not, haha "sue your teacjer " hurr durr I am so smart ahah. If that's the shit you were doing at physics classes I'm extremly sorry for you. But np you must be some american or european from the dumbed down countries ( usually the richer ones with a few exceptions ) that think they are the king of the world and woah they are so "random" and "nerdy" because they can derivate (etc) and do some basic problems at 19 yo, like 3 years later than some actually good countries
