So with Sasuke's abilities, his struggle against Deidara isn't really a feat, he never was a genjutsu specialist and possessed lightning techniques capable of defusing Deidara's bomb, while it's a vise versa in Itachi's case. Sasuke was a way too reckless, he could've avoided any problems with Deidara if he took him seriously from the very beginning. Possibly, Itachi could take on that Deidara and defeat him, albeit with great problems, but adding Sasori into the fight would leave Itachi almost no chance of victory. I disagree. Deidara can isn't immune to genjutsu, as seen when Sasuke made him believe that C4 had worked. Given that Itachi's skill in genjutsu is far superior to Sasuke's, he should have little trouble catching Deidara in one. In addition, I highly doubt Deidara can break out of the Tsukuyomi, given that Kakashi (no slouch in the genjutsu department himself, and has a sharingan to boot) couldn't resist it and Sasuke struggled to break out of a watered down version. Plus, the Yata Mirror should be able to block Deidara's attacks, and it would be hard for him to dodge Amaterasu.

Sasori would be more of a challenge, but Itachi's skill with his sharingan should allow him to dodge most, if not all, of his attacks. Offesnsively, Amaterasu would be enough to deal with all the puppets, and if that doesn't work then the Totsuka Blade should be able to seal him.

Conclusion - 8/10 to Itachi mid-high difficulty
