Yes, Hashirama is "weaker" than naruto in the sense that Naruto has:
1) superior DC ( could argue otherwise, however we didnot get a good showing of 1,000 hand bhudda- so until then naruto has > DC) I have seen people calc that 1 punch is a mountain buster meaning hashirama can quite easily destroy 1,000 mountains in moments- but until feats are shown its null)
2) Naruto has speed + reactions superior than hashirama has shown
3) have same/similar durability- naruto can tank his own biju dama + juubi lazer,- non sage mode hashirama bunkers down in mokujin and tanks bijudama- so they both have rediculous durability potential.
So, if naruto characters had power levels,- since naruto has more speed and power and the same/similar defense as hashi ( feat wise) he is superior.
-So yes, it is very possible that Naruto > hashirama from that perspective. However, remmeber hashirama is haxed.
-Mokuton is a omnydiretional attack that 99% of ninja cannot dodge, the last .9% go to sleep because of pollon. My point is that, sure in a 1v1 Naruto has the ability to win ( if we assume hashirama would be unable to subdue kuruma) however, against most ninja, hashirama has the advantage.
so, lets say both hashirama and naruto are surrounded by jounin level ninja,
both hashirama and naruto would win almost neg diff- however hashirama would have an easier time.
-hashirama claps his hands, and instantly a forest blooms around defeating all his enemies ( wethor they get cut/crushed or inhale pollen )- remember Madara created a forest easily as a edo with some hashi cells- hashirama himself could probably create a forest the size of konoha near instantly.
-In order for naruto to win, he could create 1,000 clones and fight or transform into BM and roar/bijudama- but all of that is much more effort and less sublte than hashirama senju's way of acting.
-furthermore, not everthying is about power. hashirama creating forests is more usefull than most think-
-most likely can provide food for a entre village, can grow destroyed habits, restore vitality to dieing places.
Conclusion
Naruto may be more powerful in a sense- but I would argue that at that point,- having that much power is largly useless for most situtaions that might occur in the narutoverse.- In general, hashirama is much better rounded than naruto.
