I think Rich raised a really good point, which is that just because an animal doesn't react, it doesn't mean it didn't smell you. Different animals react with alarm to different things. Bobcats, for example, have pretty decent noses, I think, but they don't seem to care about human odor even when they do smell it.
It would take some carefully controlled laboratory tests to answer this question, and even then, I think it would be hard to come up with something that's definitive. Until they do that, I think we can just say that they've both got good noses, and you'd better factor that in to your hunting plans.
