Jokes aside it really doesn't matter, Sanji had a lower bounty than Robin up until Dressrosa yet we knew who was stronger. If anyone is trying to clown Sanji just point them to Jinbe having an equal bounty to "The king of hell AdvCoc beast who scarred the worlds strongest creature and defeated the strongest YC1", the deflection from this fact has been hilarious to see. Remember that people doubted Sanji would crack a billion and thought there would be hundreds of millions between him and Zoro, but the difference is a measly 6%. The best part is they can't claim it's a gag this time.
