People should keep in mind Naruto is a 16 year old boy he has not yet reached his prime. Hashirama was a grown ass man who's had years to perfect his powers.
If you want the fight to be even then at least wait until the end of the manga then compare him to Hashirama.
This is like comparing Sasuke a 16 year old boy to Orochimaru a 54 year man not exactly even. Even someone like Itachi who is immensely powerful is only 21 if he lived its possible he could have become even stronger.
