@Mr.Grave

I wouldn't exactly say Itachi was greater than Shisui in Genjutsu. Since he's dead and we can't use Canon Feats to find out, we can only go by the words of those who knew him. It was stated that Shisui was the most powerful Genjutsu user of the Uchiha in chapter 550. Since this statement doesn't conflict with anything else stated or shown, it can't be denounced. So for now, Itachi is either weaker or just as good. But not better until it is stated or shown, but unlikely to be since Shisui and him are both dead.

As for the topic at hand. It really isn't known. Everything up until this point can really be debated since Itachi's intentions were to protect Konoha. So any Genjutsu broken could of been Itachi just going easy. Or he might have been serious. Because of the way Kishimoto wrote Itachi, it can be left too much up for interpretation.
