Yea shiki was given that hype by the mere fact that he was taking on garp and sengoku at once and it took them a day to beat him. Oh yea garp and sengoku must like destroying half of marineford and wasting more time than necessary to put down a notorious pirate. Those are feats no one can other than that tier of garp/WB and roger can compete with. Sengoku was never given that hype , ur not thinking straight if he believe fleet admiral means ur insanely strong, kuzan was supposed to be FA not akainu but akainu challenged an beat him, FA is a leadership role doesnt mean you're stronger than an admiral. your argument is pathetic cuz the manga outright proved you wrong akainu>kuzan.
who told u everyone is equal, did oda explicitly state that wb=sengoku. absolutely not marines arent always equal to top tier pirates, sure they may be close but not equal. Garp has gotten the most hype as a marine, he was said by roger to have near death battles with each other, he one shotted prime chinjao and called him a demon, he's called hero of the marines and is famous and is used to recruit marines. He easily stopped marco, the guy is hyped and showed decent feats to the extreme. Sengoku doesnt have close to that hype, sure can he give him a high diff fight but are they equal absolutely not, Oda hyped him as the strongest marine.
Your logic is astoundingly poor dont put sengoku on the likes of WB or roger oda never even mentioned him with them, where as shiki is a known rival with really good feats in his fights with garp and sengoku and you think they werent serious about a guy destroying marineford. sengoku goes apeshit when ppl leave impel down or ruin the marine name you would think he would want to minimize damage as much as possible. seriously your arguments are getting funny.
Shiki has amazing feats that puts him on that level, anyone who takes on both those guys and doesnt lose for a day and destroys half of marineford means he is very very close to roger lvl etc. sengoku on the other hand is meh in terms of hype but sure hes close but not on garp's level or shiki's for that matter.
