Exactly, it's arguable, but arguable for both sides. Yeah, Tobirama fought a lot of Uchiha clan members and knows how to avoid or to withstand their genjutsu, but as far as we know, no one aside from Itachi (and Shisui) has ever demonstrated so impressive gejutsu feats and so great proficiency in using it. Of cource, Tobirama wouldn't fall under simple Genjutsu: Sharingan, yet there's a lot of ways to use other genjutsu, especially in the case of Itachi - Uchiha commonly use the eye contact to cast it, it's not so nessessary for Itachi, as just one finnger was enough against Naruto to trap him. Tsukuyomi is even out of the question, it's a oneshot victory if it'd be cast, although the main problem is to cast it on Tobi with the same eye contact nessessary, and Tobi knows the best ways to avoid one.
