guys konan should win because she can constantly create paper harden them to steel quality and form them into weapons so she is a walking armory that never ends as long as she has chakra. And she is not hurt by fire or water if people watched her fight with jiraiya and when pain came a washed he down. And sasori's puppets are all useless in this battle (including him) except for the third kazekage though if sakura could defeat it im sure konan can since she has like 6 billion exploding sheets of paper and since she is paper she is probably immune to poison.
