Naruto wins this,
--PS slashes are blocked by the tails of the kurama avatar, it has no hopes of even scratching the avatar, whilst naruto fires off Flash TBB and continous TBB to eradicate the structure,
--Kamui shurikens are blown away by the kurama roar, or just countered by narutos own projectiles,
--outside of PS, obitos kamui warps are sensed, and the instant he solidifies to attack, he gets himself slammed down by the other multiple clones that naruto would have,
BM minato beats him as well, only he does it more efficiently thanks to the utility of FTG
