Minato vs threads are very hard to conclude for many reasons.
1) We have never seen an opponent even injure Minato in battle. Tobi didn't injure him, B and A didn't injure him, he went to face and force back Iwa and came back to save kakashi and Rin from kusa shinobi and he didn't even look winded after that.
2) No one has displayed speed that could match his FTG and reflexes so far, which is part of the reason we can't say oh sasuke will hit him with sasuno'o arrow, or amaterusu.
3) Intelligence, yeah sasuke is intelligent, but he has needed help in most of his battles, like how tobi used is ST jutsu to slow down danzo's sword from decapitatuing sasuke, giving sasuke enough time to overpower the paralysis cursed seal placed on him and activate sasuno'o, against deidara he had so many advantages with his lightning tech being able to siarm the bombs and his sharingan being able to see the mine field and. C4 nano bombs but he was still forced to injure himself with chidori to survive and taken to his limits. He is smart yes, but given the advantages he had in that battle, he shouldn't have been pushed so far, though admitedly, deidara is a very intelligent guy too.
Against A, he couldn't hit A with any of his attacks when A was at full speed, only getting his arm because well, A decided to hell with it, something I don't think Minato would do. Minato is faster and smarter then A, he wouldn't so what A did to penetrate Sasuke's defense.
Now Sasuke's powers that we have seen are a bit more diverse and destructive than Minato's, but what is that going to help when you can't hit your opponent, nonetheless sasuke makes up for his lack of speed with sasuno'o and blaze release shield, which Minato can't penetrate with rasengan or his kunai.
Now there is another matter, Minato was gonna penetrate A's armour with his hirasin Kunai when he tried to stab A on his back until B interfered with his bijjuu limb, Minato then cut the limb with his kunai, which begs the question, is there something about those kunai that we don't know?
How is it that B tried to stop Minato from stabbing through A's armour if he knew it wouldn't penetrate, B is A's brother and tag team partner, he obviously knows almost of not everything about A's jutsu.
A, the owner of the supposedly impenetrable armour thanked B for saving his hide, why would he do that if he knew Minato's kunai wouldn't pentrate? And how did the kunai cut through a bijuu tail? Surely that should be impossible for a mere kunai to do that right? Otherwise then bijuu wouldn't be feared at all, was there something else we don't know about the kunai?
We don't have absolute proof that Minato's hirashin kunai can penetrate A's armour, but the circumstantial evedience points us toward that direction, if it can penetrate A's armour though, then it could pentrate sasuno'o too.
Other questions to ask are about Minato's ST jutsu and seals. Jiraiya was able to seal Itachi's amaterusu, why can't Minato, a much better seal master do the same to sasuke's blaze release? Sure Jiraiya took too long to seal it, he had to scribble on a scroll and then slowly seal it away, but Minato has demobnstrated the ability to make instant seals on many occasions, his contract seal that he placed on tobi was instant, without any scrools to scribble on, the hirashin seal that he placed on the kusa guy that almost killed Kakashi was instant, and he only went through a feew handseals to use shiki fuin and the four elements seal placed on naruto to seal the fox, so there are signs that Minato could seal sasuke's b blaze release with ease, speculation yes, but I'm only using what I have seen from manga to speculate.
Sasuno'o, we now know for sure that a user can be sperated from sasuno'o, we saw madara get sperated by gaara's sand pulling him, so can't Minato use Hirashin to transport sasuno'o away from sasuke like he transported the kyubi, and then kill him?
He is certainly fast enough to do so, sasuno'o is fast but no where near Minato's speed, or can't he outright seal the sasuno'o away with the four elements seal or any seal he might and should have in his arsenal? Same for blaze release?
Can't he summon ma and pa and put sasuke in frog song?
The way I see it, if sasuke couldn't keep up with A's speed and had to rely on shields to defend himself, then he will have to do the same against minato who is faster, fire release and raiton are useless, no one has been able to mould handseals against A's full speed and they won't do so against Minato.
Minato can definately outlast sasuke, he used FTG to defeat Iwa, how many times do you think he used it to do that, and still had enough chakra to teleport all the way to the borders of kusa to save kakashi and rin against another jounin squad and looked perfectly fine after all that, he shouid be fine, he's a chakra monster.
I think Minato wins this, yes I don't like sasuke, but that is just because of what he did to karin and team taka, I used to be cool with him before he did that, nonetheless, I also don't like Minato, don't like what he did to naruto, though he had good reasons.
