Haven't yet tried Billy Budd (or Purple Cow), but I've been enjoying some Habana Daydream. It seemed harsh and odd-tasting at first, then I tried it in my big old Comoy's pot (0.91" chamber diameter) and it's great. It's like a nice, spicy Balkan, except the latakia's even further back and the cigar leaf adds a nice, rounded flavor, to me. I think it's got so many components that it really needs to be tried in a wider pipe.Habana is definitely rougher around the edges than Billy
