Wool has the advantage of fire resistance and longevity. Otherwise it is outperformed by synthetics, now that we understand what made wool fiber so good. But most of the synthetics are not fire resistant (this can be important when traveling, or huddling around a campfire) and gore-tex has a limited life even where properly laundered (and can fail within weeks if not properly laundered). So no choice is perfect, and every choice has some advantage even though it is often downplayed.
