As far as mihawk's comments:
Even if mihawk did imply something about WB's strength at that point he never actually got to test the difference. His attack was blocked by one of the NW's greatest figures, jozu, who had an ability which would be specifically ideal for the feat.
Another thing, this is a battle of two of the greatest figures in their respective times. MIhawk isn't just some pirate of some worth, he is someone whom the world recognizes as the world's greatest swordsman. And there are quite a few extraordinary swordsmen out there, its not like swordsmen are not mainstream in OP. With that in mind odds are that mihawk is at least at the admiral level or higher. MIhawk is someone who should actually be stronger than doflamingo whom we could argue was comparable to an admiral (though he seemed slightly beneath). So you have one of the greatest figures of the current times against one of the greatest figures from 20 years ago. Mihawk is by all intents and purposes in his prime and making this era his absolute bitch, at least in his specific area. This fight would be more interesting if it involved sengoku from 20 years ago.
Age goes have an effect in characters in this manga, even beyond specific illness. Remember chinjao? Garp considered chinjao a rival of sorts back in the day, enough to have warranted garp punching a bunch of mountains. Aging is an actual thing in the manga, even if 2 years ago they were able to do their parts in the war 2 years can make a huge difference. just look at sengoku's physical appearance, he looks like he aged 10 years. Immediately after the war ended.
