He did just beat his ass, steal his jutsu and wear him out ( And he's edo lmao )
So Madara >/> Obito > Hashirama.
Madara solos.
All hail
Counters Sausage with his eyes closed.
I see it as Alive Hashirama (after VoTE)>Current Madara> Juubito> edo Hashirama>Edo Madara
Why I put alive Hashirama as strongest? Simple, he have bijuus 2-9 under his control plus have SM which he can all use. the Juubi was made with Bijuus 1-7 and small fragments of the 8 tails and 9 tails chakra while Hashirama is only missing the 1 tails but have the full power of Hatchi (sp?) and Kurama which means more fire power. Hashirama shown to have knowledge on the Sage's jutsus by knowing the revival jutsu and I doubt he's going to know only 1 of the Sage jutsus.
Current Madara would go next for not only having Senjutsu but also have Rinnegan, Hashirama's DNA, wood jutsu, PS and I'm sure we're going to see a lot more from him now
I put Juubito next because he has fire power and can't be hurt without Senjutsu
Edo Hashirama is not at full power as stated when Tobirama said they were almost at full power
On the end notice I would like to add that we saw Madara heal himself at the end of the manga. I believe it's due to Hashirama's ability because Madara said Tsunade was nothing compared to Hashirama who can heal wounds without using hand seals. (was before she used Yin seal)
