Odds take this, they have the more balanced team, plus they have two medical ninja.
But they have no counters to any of the jutsus that the 2nd, 4th, or Naruto have.
Which one of them is going to counter a TBB? Tsunade? Hiruzen? Get real.
The only Hokages that can counter Naruto's attacks are the ones with ST, and they are on his team. Tobirama has Edo Tensei, and Minato is the greatest sealing user in the manga, (not to mention insanely fast), and he has awesome summons. The toads are the best summons in the manga by far.
Having a more balanced team won't help them at all, as Hashirama and Hiruzen don't have the speed necessary to contend with Naruto or Minato, or the defensive capabilities to stand against Naruto.
Tsunade is almost a non-factor in this fight.
