Whitebeard clashed with Oden's hardened swords without even using Haki on his Bisento.
Actually he stood up immediately, called Kaido and then cut a cross into his chest.
Roger was happy to meet Oden. Why would he seriously hurt him? Plus Oden was on guard charging towards Roger and Roger hit Oden's stomach with blunt force. Do you think Oden would stand up if Primebeard hit Oden's back of the head with his Bisento? He, would have split Oden's skull. Unless you think Oden's head is durable enough to withstand that. Oden was killed by a headshot from some average pistol. Primebeard with his monstrous strength and Supreme grade blade would had crushed Oden's skull.
So yoh basically saying what I just said
WB needs COA or Gura to overpower primé oden same way Roger needs CoA
If bass primebeard is above Young base Kaido or current bess Kaido then Primebeard shouldn't be matched by Non prime Oden whether with CoA/Gura or not.
Oda showed equal clashes :
*Young Oden matches Primebeard. (their CoC clash seemed equal too with nobody blown back)
*Young Kaido matches Oden
AP :
*Roger overpowers Oden with CoA named attack.
*Dragon Kaido overpowers Prime Oden with unnamed attack.
*Prime Oden cuts Dragon Kaido with CoA named attack
*Base Kaido one-shot Oden without COA/named attack by using one arm.
*Reminder Oden reached his limits vs Kaido not 26 years ago vs Roger or 30 years ago vs WB ! *
So tell me how where do you see base Primebeard above Young Kaido /primé oden even ? Simply bias agenda!
Cause neither WB nor Roger fought or overpowered prime oden.
Now Current Kaido uses named attacks ans has more AP, has gotten stronger, even oden told him to grow stronger.
Tell me again how does base Primebeard beats Prime Oden/Young base Kaido less than extreme diff or push Current base Kaido past high diff.
I cannot wait when Kaido or BM tank and beat Luffy (using AdCoA) low/mid diff... I wonder how you will now argue WB being above kaido/BM if AdCoA can't let Luffy +help even weaken or beat Base Kaido
