I think kuzan would win easy since his devil fruit might also be awakened and the range of hie hie no mi is incredible.

Even in marineford we saw him utilize advanced busoshoku haki when blocking Mr.Newgate's attack on marineford plus his speed is nothing short of amazing

I don’t think so bro, Aokiji would have destroyed that man anyday of the week

I think Doflamingo was already awakened when aokiji confronted him. That single scene shows Doflamingo utterly defeated by Aokiji with extreme low diff.

Ok but Kuzan's ara ara is still living in my head rent free
