I suppose one consideration might be that bears have a tendency to being pretty fat and producing sparser blood trails, and the monos have a tendency to making about quarter size holes in the hide. I have seen enough instances of caliber size holes in the hide both coming and going, even while doing incredible damage in between. I guess I'd prefer something other than that happening for black bears which in my experience are shot at close range in the evening, after sunset. I don't know how to guarantee big holes in them though.
