He got some of his power but He didn't get all of it his wood techniques ain't the real deal like Hashiramas. And besides eyes isn't everything Hashirama have the body of the younger son of the sage while Madara at that point didn't have the eyes of the elder brother he had ems not rinnegan at that point so Hashirama was stronger. We can't really tell if Madara or Hashirama is stronger atm but since Hashirama defeated him I'm sure he has a way to counter rinnegan somehow he must already know of it.seriously Madara is the strongest... after the So6P... edo Hashirama got raped by the 3rd...Compare edo Madara with edo Hashirama u can clear see the huge gap between them.
Madara surpassed Hashirama after there Battle @ Valley end. He obtained some of Hashirama's Power and a waken the rinnegan...and clearly u have seen what he can do... F.Y.I after that battle Madara didnt Die...and if u think am just makin it up go re-read the Manga where Kabuto Was talkin to Edo Madara...
for link am just too lazy to post it....
Sarutobi sealed both hokages but this doesn't mean that he was stronger then Hashirama in his prime rofl. Hashirama probably knows all techniques lol since the third was said to have known all jutsus and first was his teacher and plus he had his scroll sealed one that naruto stole in beggening of episodes.
