If Sasuke is limited to his Susanoo with an bow an arrow, then I'd give it to Tobirama mid diff.
With a V3 Susanoo there is pretty much zero chance of Sasuke landing a hit on Tobirama. Arrows can probably be evaded with his speed alone or with Hiraishin for sure. Amaterasu can be evaded with Hiraishin as well. With Edo Tensei, he has access to Gojo Kibakufuda, which will destroy Sasuke's Susanoo if it hits, and since his chakra flows through the Edo's body, he can move it around to any marking a marked Kunai via Hiraishin.
All he needs to do is evade his attacks, get a marking, a Kunai, or even a clone of his near his Susanoo and teleport his Edo Zombie right next to his Susanoo and watch as Gojo obliterates Sasuke.
Give him the one he used at the end against Kakashi and I'd say that Tobirama would win high diff.
