On par wouldn't be the right word, considering he got easily fodderized. But was this to trick to his ability to slip through stuff during the Minato fight. I think the swirly Zetsu's Dna actually combined with him, and possibly gave him the ability to teleport without the magenkyou. He uses kamui, but with 3 tomoe sharingan it shouldn't be possible.

During his Minato fight, He used the same technique he uses now, trying to suck him into his eyes, but is he not using his eyes?? Considering Magenkyou Sharingans have alternating powers, Obito can send stuff out with his Magenkyou, while Kakashi uses kamui to trap them where he's staring at. So, that would mean that the swirly Zetsu is what allow him to teleport, and go through the ground, as seen during his fight with Torune.
