So this thread were supposedly to be a reply but it got closed so I'll post it here for discussion.
So yeah, I want to give my opinion on why Sasuke can't win although he's stronger OR think that he's stronger than Naruto.
At first when Madara were introduced, you'd be thinking, Madara with EMS and Kurama can obliterate Hashirama easily.
But it's not the case, and in fact he lose to Hashi 3 times (no offense, i'm a devoted fan of Maddy here.)
It's not the plot, actually it relies much on the nature of that power Sasuke receives.
Willing bijuu > unwilling ones.
Why I say this ?
Uchiha always use Tailed Beast as their tool (or rather, Kyuubi until recent chapter)
But in both cases, they lose to someone because they think that their opponent is weaker simply because they gain control of a massive chakra beast.
That's why you see Naruto obliterate (idk the suitable word) Kaguya, it's simply because the bijuus are willing to cooperate, hence greater chakra gain (or power focused on an attack)
If they're dragged on without be willing to even use their full power, then Sasuke, can't defeat Naruto because he thinks as long as he gains control of bijuu, he'll get their full power.
Technically he needs the power of cooperation to gain perfect control of the bijuus' chakra, which is not going to happen any sooner.
For those who were about to ask that wdf Hashi cooperate with, we can safely assume that it's like Ashura.
