There is no way to compare them to each other. They work completely different on the shot. The drop away there is no pivot point and the wb there is. If the bow riser moves on the shot before the arrow clears the rest it will effect the shot because the arrow still riding the rest and the farther your rest is away form the pivot point ( straight over your hand on the handle are the hole in the riser is on the pivot point ) more it will be off the target.
