We don't how Obito cast that Genjutsu. Or if it can be practically applied in battle. Whereas Itachi have severe Genjutsu hype from many characters including extraordinary feats. Him controlling a Bijū also doesn't equate to him being impervious to any attempts at Genjutsu. He has no feat of breaking illusions and his overall portrayal in that field is poor.
