Personally I like the Brandywine HoK but I would use a lighter primer color to really make it pop. In my humble opinion I think the black would turn it into a black cherry kind of color where a lighter color primer would let the unique HoK hues do their thing.
PS. I have never seen Brandywine with black primer in person so I have no reference as to what it really looks like. I have seen Brandywine with lighter color primers and that color is awesome. The only reason I do not put it on my car is because I live in Alabama and for an Auburn fan to have a Alabama "color" on their car is bad juju.
