I'm honestly not sure if Tobirama was the best. Hiruzen definitely reigned the longest and under his rule pretty much all other legendary ninja were trained and developed, so it's no small feat he did. It's clear from the flashbacks that Tobirama was mostly the brains behind Hashirama's rule, leaving it IMHO a tie between Tobirama and Hiruzen.
