I said that Smoker did not know whether Ace had haki or not. Nothing about Ace having haki. The point of this blog is about how brave or cocky Smoker was when he was only a Captain dared to went against a 550 million man alone (he had some soldiers with him but they actually does not count imo).

Ace did not use haki even in tough fights which implies that Ace could not use haki. He did have haoshoku haki but that was dormant.

As for the fight. The jutte is indeed a factor. But Ace could have destroyed is easily imo. As for the powers. Both were immune to each other. However in terms of physical prowess I think Ace was the stronger one at that point of time (although it is mostly speculation on my part). So if that was the case then if then Ace would have an upper hand after he breaks the jutte.
