Let's see: the only way to defeat edo tensei is to seal the target and Itachi has Totsuka Blade, so that's how team Itachi is going to win. Naruto is pretty much useless in his base form, so Bijuu mode is all he's got, 5 min. max. He could launch a Bijuudama at Madara's Susanoo to throw him of guard. Bee is pretty good actually, I don't know if it's possible, but he could make Samehade shred some chakra off of madara or his Susanoo. Madara could always do the Meteorite Technique, so that only concerns Naruto and Bee cuz they arent edo tensei. Also, madara has mokuton with the world of trees and flower world techniques, so he could tame Bee in his tailed beast form and maybe Itachi in susanoo. Madara also has Amaterasu, so he could set Bee on fire from the start, and corner Naruto with mokuton and then set him on fire or just wait out Bijuu mode. Since they all have full knowledge of each other's abilities, I'm going with Madara.
