Many things i would like to say.
1) I dont even know why even if he is an Uchiha, that ppl put Itachi in the same league as Sasuke and Madara cause if you really read the Manga you'll know that Itachi was playing his role. Sasuke didnt kill him, he did and prepare everything for that day to transfer his power onto Sasuke. Madara said it himself to Sasuke bcause Itachi was sick.All Itachi did was to make sure that Kisame and the rest think that he his on their side when in reality he was protecting the leaf village, he never wanted to fight Kakashi, nor Jman.
2)Sasuke is strong but dont kid yourself cause, if you go back to since the beganing, when a fight is too long like with Zabuza an hakou, Naruto broke free, Sasuke could of been killed there, against Gara, Naruto saved Sakura and Sasuke, Sasuke could of been killed there too, against Bee, he could of been killed also but Bee wanted his fredom more then fighting Sasuke and also he got saved by karin and even Jugo saved Sasuke, Sasuke didnt kill Daidara and could of been killed there too, at the Sumit, white Zetsu saved Sasuke then Madara saved him a second time. Sasuke got saved sooo many time and ppl are comparing him with Naruto.
