User blog comment:Salubri/Aizen, Yamamoto and Wonderweiss/@comment-1752519-20100226201606

in strenght he overwhelms (ive never seen aizen cover half a city in fire or anything similar) but ill put you some facts

it doesnt matter a lot about reiatsu levels on kyoka suigetsus attack it would just determine what it can and cant cut while ryujin jakka has the strongest attack in all soul society kyoka suigetsu isnt even an offensive type zanpakuto you cant compare them in that form, with the same reiatsu put in ryujin jakka you could burn down a town while with that amount kyoka suigetu would just cut or create illusions like i said you cant cmpare them in such manner as it would be like cmparing a mirror to a flamethrower

also, unohana stated that ichigo is the only one that has a chance of defeating aizen

yamamoto was going to use a selfsacrifice technique

aizen was talking about battle power that would take inteligence out of the picture wich is also an atribute whe also cant know if he includes in that facts like speed he never said in every single aspect it was just an overall and to my understanding just about power

therefore if yamomoto was going to commit suicide, and unohana says that ichigo might be the only one that can beat aizen(unohana knowing yamamotos power as she has had hundreds or maybe thousands of years around him)it must mean that it is unlikely yamamoto could win as easy as you put, after all unohana and yamamoto himself are sure t know yamotos strength even better than aizen

either yamamoto seriously risks dying in a battle or he does something like what he was about to do and ensure aizens death and considering that yamamoto chose te second its because he knew the risk that he would take on one on one fight

aizen just isnt an idiot and isnt whilling to risk dying he has superior intelect and advantage thanks to kyoka suigetsu but he cant take such a serious risk as to fight yamamoto because of his ofensive capabilities he wasnt sure if he could win and therefore he didnt want to take such risk and yamamoto also isnt and idiot an isnt willing to risk aizen letting aizen live if he was sure he could win in a head on battle he would have done it, but he wasnt and couldnt take such risk

also what was said can be taken in difrent manners te fact that you say that youll keep quiet if i prove you wrong is because you know that if i use what aizen said youll just state that i misinterpreted it as whe took it each with our own point of views/interpetation

i dont know what more do you need to admit the are at around the same level
