Does the Akainu vs Aokiji fight lasting 10 days show that powers/styles still do matter, even amongst the most powerful?

- Luffy fought and defeated Kaidou in what, less than a day? Was Luffy way stronger than Kaidou and that's why he beat him so quickly? Was the gap between him and Kaidou so much bigger than the one between Aokiji and Akainu?
-(Zoro defeated Kaku within a day and Luffy defeated CP9 Lucci within a day, but those were weaker and effectively pre-haki characters - it seemed like the "styles makes fights" only started to end when advanced haki came into it, which is basically the characters who belonged at marineford and stronger (Luffy didn't belong there, strength-wise)).
-Blackbeard defeated Ace pretty fast too, right? Was BB just way stronger than Ace?


It seems like Akainu and Aokiji only lasted so long because of their fruit powers cancelling each other out and not because of them being as strong as each other. Another character as strong as them would lose or win much faster than 10 days.
Likewise, Ace fought Jinbei for 5 days. This happened not because they were as strong as each other, but because Ace's fire powers and Jinbei's water powers cancel each other out. Another character as strong as Ace would either win or lose vs Jinbei much faster than however long it would've taken for Ace vs Jinbei to produce a winner (they never finished their fight).

It seems it has to be the case, but it's also an insane stamina feat regardless of if their devil fruits cancelled out. Luffy fought Kizaru and both were exhausted within seemingly minutes. Kizaru did get his energy back several times but was eventually knocked out for good. How Akainu and Aokiji could have fought for that long is beyond me when they are roughly equal to Kizaru, and all three are Logias. I figured maybe it was a trait of Logia fruits but the Kizaru example proves this isn't the case.

-Blackbeard defeated Ace pretty fast too, right? Was BB just way stronger than Ace?

Yes. Shanks knew that BB would destroy Ace if they fought.

Didn’t Akainu melt the ice Jozu threw?

I just reread it and he did melt through the ice several times. However on Punk Hazard it's made to look like their abilities cancel out. There were two biomes made by their powers and it seemed like the fire side wasn't overpowering the ice side.
