the way i see it the main threat kakashi (because of kamui) will be killed quickly because of susanoo aroows. sasuke will outast guy because guy cant break a susanoo wraped in amaterasu, but guy can dodge susanoo arrows and avoid eye contact and he does have hirudora which is very powerful unfortunately it didn't kill kisame so i doubt if it can break an evolved susanoo wrapped in amaterasu. guy has one offensive jutsu that he can use againt sasuke while sasuke has all his blaze release jutu, susanoo arrows, susanoo sword and genjutsu.
if guy stops even for a second or two he could be burnt by amatersu, put in genjutsu or hit by a susanoo arrow. remember the 7th gate tears all your muscles apart so when the gate is closed its over for guy. dont underestimate sasuke's skill in genjutsu he has a 4/5 and it was enough to confuse danzo who is more resistant to genjutsu than guy, if guy gets confused by genjutu for the slightest moment then sasuke can use susanoo arrows or enton magatama or amaterasu
people dont understand that sasuke can just prevent kakashi from using kamui by spaming susanoo arows and he can fill the battlefield with amaterasu or use genjutsu like how he defeated danzo. if he could decieve danzo a master of genjutsu then he can decieve guy maybe even kakashi. they can fight when the ground and the surroundings are covered in amaterasu
sasuke high diff (when guy can break an ems suasanoo wrapped in amaterasu+ the threat of tsukuyomi and susanoo arrows then he'll win untill then sasuke takes this.) also launching a flaming susanoo arrow into the sky should allow him to use kirin
and for the ohk kamui check my previous posts.
