Boruto vs Naruto Sage Mode, but without denying reality this time
Base Boruto could probably do this even with a chakra-infused twig from a nearby tree.
Evidence: the manga
Jigen was already massive powercreep as a character as he beat Naruto and Sasuke 1v2. Jigen is then dwarfed by Isshiki, the Otsutsuki really incarnated. Who didn't just beat Naruto and Sasuke, he styled on them (lil reminder, Surfboard-Sasuke)
Boruto is at minimum stronger than Jigen as he beat an even stronger Code. And yes, Code really is that strong:
I think we can trust the lil guy who probably is top 1 of all time when it comes to sensory abilities (who tf can sense the whole earth trembling a wee bit when that trembling was so minimal that nobody else could notice it?!)
And it's likely that Boruto is even near or at the same level as Isshiki. Where does Isshiki scale? Ideally, he'd need feats against Jigen since the latter is often used as a benchmark. But that is impossible due to obvious reasons. All we know is that reincarnated Isshiki is a lot stronger than his Jigen self, both clearly shown by Kashin Koji's reaction to Isshiki's power and Isshiki very easily beating Naruto and Sasuke
Who else is much stronger than Jigen? Daemon and Boruto. Daemon was even more impressive as he only used taijutsu to easily beat Code. But Boruto too is by all means quite a bit above Jigen since he could physically keep up against a stronger Code just fine and easily beat him with a single ninjutsu.
Idk how anybody can read the manga and then think adult SM Naruto beats current Boruto. Adult SM Naruto vs Borushiki (not in current Boruto, I mean in 12 year old pre-ts Boruto ofc), now that would be a closer match in which Naruto could win.
But post-ts Boruto? You can add KCM, six paths and everything prime Naruto had AND prime Sasuke and they still lose. Boruto most likely still wins even if you forbid the use of ninjutsu for him since his stats should be above Jigen by quite a bit now (meaning he too can just go through a perfect Susanoo with a normal ass flying kick and is way too fast for Naruto and Sasuke)
Even Baryon Mode Naruto beating Boruto is questionable to say the least. BM Naruto couldn't even deal significant physical damage to Isshiki when the latter didn't even try to stall and outlast him, just some bruises here and there. So it's very possible that Boruto could even win against BM Naruto by outlasting him.
And as some may try to argue about experience as a factor that could make Naruto win:
-experience is only a factor until your opponent doesn't outscale you by several tiers
-experience stopped mattering against Jigen already, the man was breaking through a perfect Susanoo by just jumping straight at it with his leg stretched forwards
-Daemon, the cyborg kid who is carried by Shibai cells, gave Code one hell of a beatdown despite Code using Karma there iirc (it gave him all of Isshiki's accumulated battle experience and didn't matter in the slightest)
-Jura, the new powercreeper character (going from Jigen>>Naruto and Sasuke to Jura>>Boruto and Kawaki) beat Boruto down. Jura, the lad with nearly 0 experience on ANYTHING, beat Boruto, a trained shinobi. Even Kawaki with Karma wasn't taken seriously by Jura at all despite Kawaki also accessing Isshiki's battle experience
Conclusion: Boruto is AT LEAST a bit stronger than this guy:
And possibly even way stronger than that, strong enough to use prime Sasuke as a surfboard too (Isshiki level)
Boruto vs adult Naruto with just Sage Mode (what in the spite?!) in a nutshell:
Note: this post doesn't mean I dickride Boruto and hate Naruto btw. Boruto is simply much stronger due to the massive powercreep being used to keep the cast of important characters small
