I don't see how considering Sasuke lighting release beats the First wood,water, and earth release. Sasuke has a counter for almost every justu he has.
Madara and Sasuke have different release which means Sasuke has a different chance of beating the first.
It's True That Sasuke Possesses A Type Advantage Over Hashirama, But That Doesn't Necessarily Imply That He'd Win Because Of It; Hashirama's Techniques Were On A
Whole Different Scale, Even When Compared To Madara's - And Even A Weak Element Can Overpower A Strong One, Depending On The
Level Of Chakra Put Into The Jutsu.
Handling Amaterasu Would Pose A Sticky Topic Though, Seeing As Madara, Who Also Fought Him With The EMS
Supposedly Had Access To It, Yet Failed To Incinerate Hashirama Through Its Use; The Only Jutsu That Would Prevent Amaterasu From Being As Effective Is The
Bringer Of Darkness Technique, Which Completely Blinds The Opponent ... But Even Then, They Still Have Their Other Senses, And The Loss Of One Sense
Sharpens The Other Four, Making Amaterasu A Usable Technique Even
Without Seeing The Opponent, Albeit With Somewhat Lowered Accuracy. But This Leads To The Point I Made Before - There Just Isn't Enough Info On Hashirama's Techniques To Make A Stable Prediction; If He Was Able To Deal With Madara, Then Surely There Must've Been Some Technique (
That Hasn't Been Shown Yet) Which Allowed Him To Do So, Which Would Enable Him To Deal With Sasuke Similarly.
Also, Remember That This Is
Madara Uchiha We're Dealing With Here, The Shinobi Who Had Access To The
EMS & The
Kyuubi. And Would've Stood At The Top Of The Ninja World Were It Not For Hashirama; And The Two Have Clashed More Than Once; For Him To Either Win/Tie With Madara And Still Leave The Battle With His Life Intact States Just How Powerful A Ninja Hashirama Was. Of Course, Sasuke's My Dude, And He's Grown Extremely Powerful, But In My Book It'll Be A While (Or A Few Chapters At Least) Before He Succeeds Madara In Terms Of Power.
Yeah, but I'm still sure Hashirama would win.
Oh and by the way, Madara has Amaterasu, right?
It Hasn't Been Shown As Of This Point Yet, But Seeing As He Has Access To Susano'o, It Can Only Be Assumed That Madara Likewise Has Awakened Tsukuyomi & Amaterasu; Both Techniques Are Required Before One Can Utilize Susano'o.
