[Star Trek] Which Starfleet captain has the highest enemy bodycount?

Of Kirk, Picard, Janeway, Sisqo, and Archer

Or anybody else that has taken the helm temporarily or permanently like Riker or Sulu.

Confirmed kills would be Sisko. Being in the Dominion War, they took out entire fleets of ships and bombarded planets.

Unconfirmed kills would go to Janeway. She may have killed every Borg (we don't know at this point).
