Luffy and Sanji have the same physical power as Zoro but Zoro increases his physical by exercising everyday in morning, afternoon, evening and while sleeping. His Swordsmanship power also depends on his physical strength. Luffy's DF allows Luffy to gain his physical strength and Sanji's control on his legs helps him to gain his physical but their physical increase as they fight.

Luffy's regular Gomu Gomu No Pistol send the local sea monster flying. Sanji's regular kick send the Sea Cow of Arlong crew flying and Zoro send the Sky Shark flying with his regular punch. That means their physical is same but if Sanji and Luffy didn't use their abilities then it would have taken them really long to defeat those pasafistas. a true fighter fights according the situation. At the end of the day all three of them are the Monster Trios.
