Minato has access to Sage Mode as well, since he couldn't have possibly learned it after he died. If push comes to shove, I think it could be a tie. Minato has the speed feats capable of keeping Naruto on his toes, but Naruto has the Rasenshuriken. Minato can easily boost the power of his Rasengan, so there shouldn't be any reason why he couldn't make a Big Ball Rasengan or an Ultra-Big Ball Rasengan, and they can cleave away mountains if they explode. That would be his only bet in matching the power of the Rasenshuriken.

But anyway, theories aside, I think it could tie.
