i doubt muu could beat shisui or itachi in a fight since they just have too look at him and his invisibility is not instant it takes like 2.5 or 3 seconds which if not mistaken is enough for shisui or itachi. muu cannot become invisible faster than itachi or shisui can use their techs. with all due respect to muu fans but if he becomes visible to use jinton cant itachi just use tsukuyomi?
mu cannot beat sasuke because in order to use jinton he has to become visible then sasuke can just use arrows of susanoo to finish him, and if he stays on the ground sasuke can cover the battlefield with amaterasu having invisibility doesn't mean much against susanoo.
obito and madara are obvious
muu> all uchiha except sasuke, itachi, madara, shisui, obito (because itachi and shisui are OHK's and susanoo will make muu have to become visible to use jinton which will make him vulnerable against sasuke's arrows, amaterasu and itachi's tsukuyomi)
