But the only difference is that Tobirama's technique is more of a high level and far more dangerous? He invented Edo Tensei, so we know at least that he has some capacity to manipulate the soul. For all we know, he was trying to do something similar to Obito. There's no way to know, just as we don't know what jutsu Hashirama gave him.
