I don't think he'll beat Tsunade with anything less than the 7th, and those gates he can't keep up for very long.

But again: exceptions. Most of the time, the leader is the strongest. Even with the 4th war alliance, the Hidden Cloud was the strongest, and the Raikage was probably the strongest of those Kage.
