I think it was stated in one of the data books, but i don`t know if it was really stated that he is the greatest or that he is just very skilled at it.

In all fairness, Kisame`s feats with water style far surpass everything Tobirama has ever shown. Actually, Tobirama showed very few water style techniques. I can only recall when he used it against Izuna and in the 4th war to cut some of the Shinju Tree`s branches.Not enough to back his supposed water style greatness in my opinion.
