'''The technique has a drawback. If the caster of the technique is interrupted in any way while transmitting chakra to the bodies being used as part of the technique, then all of the bodies will stop moving and become very vulnerable to attack. The Deva Path, through Yahiko's body, was momentarily interrupted while it was fighting Naruto, allowing the latter to easily land a punch on the enemy.'''

This technique relies heavily on transmitting Chakra. Kamui'ing them all away gives Obito the win. Genjutsu also is said to be Rinnegan's weakness, and Obito is an Uchiha. Obito has Kamui to avoid every attack any Pein has and can get close to each and everyone of them without repercussions. All in all, Obito wins with Mid difficulty. Just kamui'ing them is the easy answer, why else is Nagato moved to a range close to his Pein's? Cause obviously he needs to transmit his Chakra. If he can't, then the Pein's don't work.
