Were do people keep getting this it will turn into a susano battle nonsense from.
Anyway to answer your question No, you are wrong, both have their advantages and disadvantages. First of all sasuke had the stamina advantage by 1 + the cm2 and itachi still went the distane with him. Both collapsed due to their chakra reserves, itachi couldnt recover due to his poor healthy prior to the battle. Sasuke was more or less at his physical peak but also got first aid from tobi. However it seems the ems allows the user to use its technique's with minimun chakra drain therefore sasuke still holds the stamina factor. Katon variations wouldnt be a factor this time round because sasuke's katon got a power up due to the cm2, he doesnt have that anymore
Genjutsu wouldnt be a factor, cause of the sharingan. Taijutsu also wouldnt be a factor because of the sharingan, but also but have susano and v1 is enough to protect them. Sasuke has the advantage with enton although that itsnt clear. Both have shown the ability to extinguish amaterasu, whether either can extinguish each others amaterasu is something i dont know. If they can then Enton wouldn't be a factor if itachi can extinguish sasuke's amaterasu.
Sick itachi lacks eye sight and reflex ability, although he still holds the slight speed difference. Zetsu noted that itachi shouldve evaded sasuke's shadow shuriken technique and that there is something wrong with itachi. Because of this, itachi would struggle with susano arrows and blaze release magatama
Sasuke has the stamina edge and the variate in ninjutsu simply because he has shown us more outside genjutsu which is itachi's speciality and ms techniques. Itachi's edge is his calmness and analytical ability, he never seems to panic. Also note is his hand speed and the unpredictably of his techniques. Terms of handspeed sasuke still wouldnt be able to read them therefore the unpredictability is there and with has already created 3 attacks in 1 move twice. Second unpredictability is his ninjutsu and exceptional use of bunshin's. Regular kage bunshin exploding could catch anybody off guard. Second is his use of karasu bunshin which disperse and temporarily block his opponents eye sight.
Seems however that sick itachi is underestimated even though he still holds the highest stats in the DB and if you were to compare his stats with jiraiya you'd note that he has better stats in majority of the categories than jiraiya. Tobi also stated that if itachi wanted to get rid of sasuke he couldve. Even with all the advantages sasuke had, he still didnt kill itachi.
Ems sasuke will beat Sick itachi 6 out of 10 with difficulty
