What's hilarious is that the fan made YC tier system lives and dies by bounties. Cracker is only ranked below Smoothie because he is said to be a YC3 and he is only said to be that because he has a lower bounty than Smoothie, don't look for consistency here, did you not just read the comment from the dude that placed Ulti above Sasaki because she took Yonko attacks but then put King far above Queen because he kicked a boat while Queen survived a barrage of attacks from big mom then proceeded to capture her yet that logic doesn't apply here even though King has no "feats" against a Yonko.
It's an absolute shit storm of headcanon and bias; all you have to know is this one important thing, the beast pirates are a strength meritocracy(canon term) which means Strength=Power=Authority=Rank, Jack is an exception because he shares rank with King and Queen but doesn't share authority or power since he is subservient to them so he would obviously be weaker but King and Queen have equal rank, power and authority in the crew so the only two logical options would be that they're either equal or King edges him out similar to Kaku and Jabra, the whole King>>Queen is utterly laughable, its King ≈ Queen. Bounty is a good indicator of strength when it comes to arc specific antagonists that won't ever really be expanded upon, especially if they are in a crew that is completely based off of strength, which is exactly why they judge strength using bounties thus placing Sanji as the number 2 early only in the raid and it's also why Marco used the bounties of King and Queen when commenting on their strength.
Anyway don't take most of these people seriously they were also talking about how Whos Who is stronger than Queen because he wanted to "kill him", turns out Whos who was just following Queens plan to ambush X-Drake......yes the same "incompetent/useless Queen" that stopped Big mom(could have tossed her ass in the sea), the same one who stopped Luffy and Zoro from reaching the roof, the same one who killed multiple alliance members with his plagues almost taking Hyogoros life in the process etc etc. This same symphony will be played when they take on Admirals, thankfully the fandom already agreed on the fact that Admirals are all on the same level, but I can't wait to see the necessary "Low Admiral 3", "Mid Admiral 2", " High Admiral 1" and of course " Elite Admiral 0", then they will create massive gaps between them thus subsequently deconstructing power scaling as a whole just because they can't admit that Zoro and Sanji are comparable.
