Naruto, on the other hand, has his abilities showcased when he was younger, so of course he isn't going to be as powerful when we compare the two considering the different in age and experience. He does easily match Hashi's abilities in Gaiden though. I was going to say the same. Also, hashirama was a prodigy whereas Naruto had trouble understanding even basic stuff. I mean, Naruto had pretty good intuition with jutsu but it required so much effort to learn more complex things. Hashirama, as said above, was killing adult Uchiha a kid.

So why is Hashirama that much stronger? because Hashirama was actually a capable ninja from the start. Naruto's capabilities as a Transmigrant lag years if not decades behind Hashirama, but the Boruto movie basically confirms that Naruto and Sasuke's powers are equivalent if not beyond Kaguya's, so he's definitely surpassed Hashirama
