team 1 high diff.. going by your restrictions.. ms Sasuke > sm Naruto - im not sure if Jman can beat Oro.. depends on edo Hashi/tobirama
No Edo...
Team 2 wins. Both Orochimaru and Naruto are needed for plot, whereas only Sasuke is needed for plot at this point (remember, Jiraiya is dead).
But away from plot, Orochimaru can take MS Sasuke and SM Naruto can take Jiraiya
This matchup is purely based on abilites... And it's more likely that Oro is going to take on Jiraiya...
