I will take a lung shot over any if at all possible, unless its a long distance shot, then I hold center shoulder. I do this mainly so the deer bleeds out, you shoot one in the heart/lungs they do not immediately die, they bleed out inside, head/neck shots kills instantly but then its a bloody mess to clean up.
shot one in the head this summer on damage permits, I had 2 big mature does that I wanted to take and they saw my buddy who was with me, one would not turn broadside so I took them both out but one was shot in the nose looking straight on, cleaning them up there was a notable difference in how much blood was still in the meat.
I can hit them wherever I want if they offer a shot, I once shot one in the head at 611 yards, because she was wounded and I did not want her to suffer. but the absolute best shot is the double lung shot without a doubt.
