Bold doesn't make any sense.Except Obito isn't Orochimaru, so I'm not seeing any evidence of Orochimaru having more chakra than Current Orochimaru, which is a laughable thought anyway.
And stop arguing that Hashi DNA/Zetsu body doesn't give you stamina/chakra boost because it does. We've seen it through Danzo and Obito and now we are talking about full Zetsu body.
