Hashirama. Most of Hashirama's abilities can be accessed without activating Sage Mode opposed to Naruto who has a number of Rasengan variants that can only be achieved in conjunction with Senjutsu or tailed beasts. Naruto would be stuck with no more than Shadow Clones and the basic Rasengan(he uses senjutsu to throw Rasenshuriken).
The only other part worth considering is the question of who's faster and who's stronger & I feel that goes to Naruto, with chakra maybe leaning towards Hashirama. If we're referring to a fight-fight rather than the general question of who's stronger, I feel Naruto should pull off the win simply because Hashirama's amount of techniques stop mattering when they're unable to actually snare Naruto. Naruto could stand toe to toe with Momoshiki in base when Obito was blitzing Hashi(I'm not sure if he was in SM at the time).
Consider the fact that both Madara and Hashirama were beat to hell. The only difference from this Hashirama is that he never summons the Thousand-Handed Senju, so this Hashirama only has more chakra going for him. My view? Base Naruto >>>>>> EMS Madara.
