Sasuke wins this mid diff at most
--Chakra directly from hagoromo as well as half of it, means that his chakra is superior to obito thereby leading to stronger susanoo which eradicates obitos PS with ease
--Enton projectiles counter kamui shuriken just fine, so even that is not working for obito
--Once PS is busted, Sasuke uses his S/T jutsu to severe Obito in half, the moment he solidifies to attack, and with sasuke being able to locate him once he solidifies means that obito stands no chance
