Complete different lvl, both we have equal battle with Oden vs Kaido, both seems almost equal,
Kaido fear Oden and make a long ass plan to beat him. Overall a battle of two solid top tiers back then.
Right under you see the Gods of one piece, the strongest characters overall, just their insane haki clash shock Oden and let him fear, Oden was complete portrayal as someone who is league under these two monsters and as
@comrade said in the past neither Whitebeard or Roger use their strongest ability here, Whitebeard didn´t even use his Gura power, just his insane CoA already do that epic clash.
Kaido vs Oden= Fight of Kings
Roger vs Whitebeard= Fight of Gods
No wonder why Sengoku, Big mom and co still fear Whitebeard until his death, portrayalwise Whitebeard and Roger are the nonplusultra of the verse. I hope the Yonkous can show soon enough good feats too.
