The question of which one is better and which one is best only applies to pistols known not to be on the same level regarding: reliability, durability, manufacturer's name and track record, warranty etc.. These two happen to be on the same level in my opinion. "You" need to research both, hold them and shoot them if possible, determine what options you prefer then determine which is best for you. They are both good ones. I've seen some really good deals and numerous selections on NIB XD's at Bud's gun shop.
