It has a little less, but you can do this with the Mad Dog by adding the treats. You can literally match the frequency response that way. What you can't match is that the Pro has a more rigid baffle, which opens up the soundstage and increases detail (without brightness).
From trade shows and meets, I've found most people prefer the Pro, but there are people who prefer a more intimate sound with less soundstage, and for them the Mad Dog with treats may provide a better fit.
Hope that's not maddeningly unhelpful.
