I have never hunted blacktails, so I dont know about them, but between a whitetail and a muley, its kind of a toss up for me. We don't have the mule deer numbers around here like whitetail, so for numbers and areas to hunt, the mule deer is much harder in that aspect. If your talking trophy hunting, I dont know if one is easier than the other, a big buck of either species is not an easy task, even harder if your not hunting during the rut. I love the challenge of both and love the difference in hunting each.
