Queen is getting choke slammed and this time with advance haki attacks. Queen is going to above King in regards to strenght, durability and endurance. He literally has the best Dinosaur fruit without a question. King is strong in another way. I think they're around the same level just strong in different ways. Just like how Zoro is strong in a different way than Sanji even though they're nigh equals.
(Screech at me all you want Z boys, you know it's true.)
