Firstly... Naruto is still has all The Kekkei Genkai like Lava and Steam given to him by The Bijuu, which allows him to increase and amp his abilities and stats greatly... Which we see him do many times with Rasenshuriken...
Secondly... He still has Sage Mode, which by his own words is more perfected to the point he can use it for longer, and enter it much much quicker then before... We even see him in the Dark Chakra Beast Arc of Boruto, to be-able to enter Sage Mode similar to how Koji Kashin is able to do it.... Sage Mode is basically allows him to recharge his Chakra like a Battery, he practically can't run out...
Nextly.... In both fights where Naruto "needed" 6PSM to battle against Momoshiki and Delta, its narratively suggested that he did need these forms to battle and beat them... BUT, in The Delta fight, Base Naruto was casually dodging and blocking blows from Delta, then proceeded to Slam her into the Ground, and the rest of the fight he was holding back with 6PSM... And the Momoshiki fight, a Base Naruto who's weakened mind you, was capable of Dodging, Blocking, and Tanking attacks from Fused Momoshiki... Mind you this doesn't mean in Base or Sage Mode can beat Fused Momoshiki, but its proving how fundamentally powerful Naruto is...
Next lets talk about BARYON MODE... Baryon Mode works by colliding both The Bijuu's and Jinchuuriki's Chakra together similar to The Nuclear Fusion of The Sun (Which Kurama saids himself) Therefore both Naruto and Kurama are putting equal parts Chakra to make The Baryon Chakra... And Guess What... Naruto Survived... Yes, Narratively Baryon Mode causes The Death of The Bijuu by extinguishing their chakra to 0, but it still fundamentally works by using both Chakra, not just the tailed beast... Meaning Naruto Overall, Naruto has similar Chakra to Kurama, not half Kurama, FULL Kurama, which puts Naruto's Chakra, His own Chakra on par if not greater then Hashirama's, which technically means he does have more power, which is narratively True as-well...
Lastly... in Chapter 65 (iirc) Borushiki was entirely willing to Teamup with Code to fight Naruto, who also took Shikamaru as a Hostage, if you're stronger, you don't do this... Code once said he could beat Naruto, which we learn was all talk, bc the Moment Naruto arrived and blitzed passed Code to get to Kawaki, Code grabs Shikamaru as a Hostage, and suggests to team-up with Borushiki, who was entirely willing to do so... Meaning Naruto in Sage Mode, was stronger then both at the time... Which can also be backed up by Naruto unfazed by Borushiki's Massive Rasengan, and was entirely confident in tanking it, also after sensing Code's Energy he was confident in beating him... So, Yeah, Narratively Code and Borushiki should be stronger than Naruto, but by showings, and the way they acted, Naruto is shown and implied to be stronger than both...
So... All in All... Put some respect and confidence on me boi.
