Well sorry if I misunderstood but I thought haki mastery means the same as haki strength.

Well Caesar is NOT stronger than Vergo, I agree with THT here (and we rarely agree). Caesar said to Luffy that Vergo is a monster who would finish off Law and Smoker and deal with Luffy's gang. He said that when he mentioned DD and the Yonko as monsters, while reffrring Vergo in a similar class. The conversation implies he regards Vergo at a higher level than him.

Law commented before Smoker joined the battle that only Vergo's arrival ruined his plan, as Caesar was already present there from before, it implies that Law regarded Vergo as a bigger threat than Caesar.

Honestly, Caesar might have a strong ability, but if his element of surprise is gone he is no match for big dogs.
