Whitetails are eaiser to pattern, and often will use the same trail to and from bed, much more often than a mulie will. Mulie often live in open terrain, where there are no trees, so spot and stalk is the most common way to hunt them. S&S is not as easy as an ambush, from 20' up a tree, over a well used trail. More whitetails also, so by a numbers game alone, whitetail is easier.
