Keep the "equal" faith. A supporting character will never be the main character, but if you repeat it often enough, your mind will believe it all the same.
true...Sasuke is about as relevant as a punching bag.
Kishi's proven a lot of times that he's made naruto and sasuke "equals". And technically yes they are basically equals, they both get power ups after the other.
On to the point, When naruto had just half of kurama's chakra, all sasuke had was his ms and so forth. When sasuke got his susanoo, kishi came up with an idea to give naruto something of similar nature (kurama avatar).
Just like how when they both died, in order for naruto to have a significant boost in power kishi gave him half of each beast's chakra, this made naruto a "mini" sage, topping it off with the moon/sun seals for both heroes. While also dishing sasuke some hashi cells in order for him to get one rennigan (respecting his own rules for once), now in reality based on fans and what we see in the manga...naruto might seem stronger than sasuke, but as long as plot protects them both...they're equal.
Eventually naruto will get the remaining other half of each bijuu's chakras and become complete sage. By then, sasuke will have the other rennigan and unlock even greater abilities so he stays on equal footing with naruto. My point is, sasuke might seem not as relevant as naruto has been (he's been putting in work) but eventually, if the plots stick to its ways since beginning, sasuke will get another power up along with naruto.
(just trying to get a point across, hopefully it made sense) Also dont forget that sasuke doesnt fully understand his rennigan.

I don't think sasuke will get the other rinnegan because of plot, since I don't think naruto is going to absorbe the other parts of the biju for the same reason. naruto wants to free the biju. he can't get them out of himself because he would die, but the parts that are within kayuga he can set free without taking them inside himself, like he did with obito.
if he get's the second rinnegan it will be for another reason, but both of them are already quite OP so I don't see the need for another powerup after they beat kayuga
