If you think an admiral is 6 when Roger/Whitebeard are 10 then your statistics are totally out of order and are wrong according to manga. Garp said that marines can't butt heads with Rayleigh and Whitebeard at the same time while putting Rayleigh on the same table as Whitebeard.
well the admirals trio are quite weaker than prime garp, WB and roger. I would rate them 7.5 to 8 compared to 10 and prime rayleigh is a 9. if akainu cant beat a WB who is old and ill with a lot of damage compared to a WB in his prime who is faster and has better observation haki he is going to get lowest lvl of high diff. prime WB, roger and garp are the strongest characters so far in the show with prime rayleigh, shiki and sengoku being close. the admirals such as kizaru, akainu and aokiji dont make that tier quite yet.
