Lucci of course.... Luffy figured Croc's weakness pretty easily..

While Lucci was the only one that tried to kick his ass with physical strength.. But he failed..

Then I would say Moria... Cause Luffy was fighting time, and he had to use everything.. Gear 2nd and Gear 3rd... Lucky, Kuma saved him from the pain (Poor Zoro)
