minato would win easily
Minato is the type of person who doesn't need a lot of jutsus, seals or power to win a battle. I still wonder why ppl still think that the more jutsus's or power you have, you are automatically going to win a battle. To great power comes great risks. To have great powers you have to know how to use them. You can not use your powers recklessly like sasuke does. He overuses his powers immediately summoning his strongest power.
Minato has the ability to stop time when he marks you. Minato is just not going to appear next to you. By the time the opponent notices minato the opponent is already going to be stabbed. For example, in the battle against madara. Minato managed to mark madara and by the time madara noticed minato he was already stabbed with a kunai and minato had already prepared a seal to take away the nine tail demon from madara's control. Another perfect example is when he teleported away the nine tail demon fox from konoha to where he had his marked kunais. You have to keep in mind that this is happening rather quickly because minato teleports the nine tail demon fox right as the nine tail demon fox is about to use his blast. By the time the nine tail demon fox blew his blast, minato appeared with his wife and son in a safe location. The nine tail demon fox blew up the house where minato's wife and son were. I really hope you see what I am saying. How can you teleport the tail demon fox who is just in the verge of shooting its blast and still have time to take your family away to a safe spot. He had to stop time, thus the reason it's called space/time jutsu.
I don't care how powerful naruto is right now, if minato can teleport away all his attacks and basically dodge every single attack from naruto since minato is able to manipulate his time/space jutsu to perfection, I am sorry but there isn't really anyone who can win a battle against minato.
I mean once minato marks you, it's over.
Naruto might have surpassed him in rasengan but he hasn't surpass him in other things. If naruto someone how learns minato's time/space jutsu then maybe but I still strongly believe he has a long way to go. He is sometimes too reckless.
