Obito wins this decisively
--Madara in EMS form lacks the reaction feats as well as the reflexes to evade kamui,, not to mention that he doesnt have any attacks that have the near FTG speed, and he also cannot attack him consecutively for 5 minutes straight
--Madara also lacks the sensing abilities here to act prior to the warp seeing how its speed is doubled here due to obito having both the eyes,, which means that Obito can simply phase through all of madaras attacks and proceed to warp him,,,
--PS and Susanoo variants, as well as Katons are not doing shit since they are simply phased through and rendered useless by kamui
