Queen the Plague is one of Kaido's three right-hand men, and that automatically makes him one of the strongest pirates in the arc. His bounty of 1,320,000,000 berries indicates that he's extremely dangerous, and he definitely proved that in the arc.

Queen is powerful and possesses the power or the Ryu Ryu no Mi, Model: Brachiosaurus. This devil fruit grants him immense power and durability, as seen throughout the arc. Despite Queen's strength, however, he will eventually fall to Sanji.

Sanji finally met his match on Onigashima, in the form of Queen the Plague. With his immense power, he has been able to push Queen back without much trouble. Sanji has also fought both King and Queen at the same time, which goes to show that he's extremely powerful.

What's more, he hasn't used his Raid Suit against Queen so far, and despite that, still appears to be at an advantage. It's also interesting to note that Sanji has already been heavily injured by Black Maria, which means that at his best, he is even stronger.
