Like others have said neck shots can be good if placed properly, (spine) but if not then you condem the deer to die a miserable death if you blow out the throat and don't hit the spine. If it's a close range shot and your sure of your ability to hit what you aim at then go for it, if not then go for the heart/lung shot. The deer will run off but not far and will usually leave a blood trail that a blind man could follow.
