The reason for saying this was naturally because the Egg-Egg Fruit's awakened effects were extraordinary, far beyond what ordinary Zoan-type Devil Fruits could compare to.
After awakening, ordinary Zoan-type Devil Fruits generally enhanced vitality and recovery. In practical terms, that meant becoming exceptionally hard to put down and possessing tremendous stamina. Such traits offered a major advantage when fighting opponents of the same tier, but relying on them to challenge someone above one's level was unrealistic.
