DMS Obito wins this
--The only attack for Juubito that will be sufficient enough to damaage the rikudo amped PS is the Juubidama, however to do that juubito needs to form the tree therefore allowing DMS Obito more than enough to eradicate the tree through PS Slashes or warp it away through kamui shuriken
--Obitos TSB based attacks are also non factor they are not scratching the rikudo amped PS nor are they negating any of dms obitos kamui based attacks or PS
--Obito has more than enough reflexes to react to Juubitos shunshin meanig that even blitzing is not happening, as he proceeds to overwhelm Juubito through PS slashes, kamui shurikens and kamui raikiri
