Akatsuki hands down.
Nagato and Deidara could destroy the village in one shot using Shinra Tensei or Chibaku Tensei in combination with c3 or c4.
Sasori and his puppets will take out any survivors with his hundreds of puppets.
Kisame and Itachi will take out the still alive A and Bee.
Kakazu will collect new organs and leftover coins.
Hidan will not be needed except to hunt down the fleeing chunin and genuine and mothers and children to massacre them and Zetsu will eat the leftovers.
Tobi would not get involved except to teleport to Kisames battle with Bee and wait till Kisame has drained all of his chakra and kidnap Bee and store him in his realm.
Konan will do s celebratory dance of the shikigami to entertain the Akatsuki lol.
