Yes.
That was my answer. Yes, the heavier ball will travel faster. It is human response, when two objects of dissimilar weight are held, generally the lighter one will be released first, this already skews results, then there has to be plenty fall time to allow effect. I would think, that if you were to further extreme the circumstances, maybe change the falcon feather and hammer to a single piece of goose down and a jumbo jet, dropped from the height that a jet travels. Which one of these two objects do you believe would impact first? And, yes that is the same difference!
