I am not bashing Hashirama,he is very powerful shinobi in the series .However there come a time that new generation can surpass the old generation.Hashirama was not known for his speed in battle but rather his healing abilities and mokutan only,therefore he cannot dodge any of Sasuke speed spam jutsu like amaterasu,kirin,chidori nagashi and ethon arrows.There is one chance that he can use mokuton to block Sasuke attack but it will be useless since Fire and lightning release >wood release.
Hashirama's wood dragon ,wood golem and wood budha can b demolish easily by Kirin that demolish an entire mountain the surround forest low difficulty .Hashirama instant healing be his own flaw because if Sasuke hit amaterasu on him then his body will have to focus his chakra more on healing the spreading flame that cannot be extinguish that using jutsu or other skills.Hashirama flower's pollens will be useless against katon or amaterasu .Hashirama's Forest world can be chop to many pieces by complete susano with legs.Susano cover with amaterasu will protect Sasuke from any budha or any wood summon because they will get burn by touch
I surely believe that Hashirama is out class by Sasuke
