Hashirama wins. Just cuz you say they are weak doesnt exclude your own weak ass arguements.
He did supress their personalities but He could still bind them and control them at will. All except for Hashirama because he is too strong.
If Itachis Genjutsu is so strong he could free himself but it took Koto the strongest genjutsu to break the Binding. Itachi described it as layering one spell on top of the other.
Madara undid his binding and Hashirama effortlessly was broke his with a smile on his face.
Madara is the strongest Uchiha and he couldnt beat Hashi with Genjutsu. He knows it takes moresouln that. You still have to realize that also.
Sasuke himself, a guy that imprisoned 9 bijuu(best genjutsu feat by far) didnt bother using Genjutsu on Naruto(Hashi's Successor).
Fail again where is yall manga knowledge at... Im not going to gi all the way through this im just going to counter your vital points of yoyr argument
1. You say madara's genjutsu hasn't worked on hashirama... Answer this... How many times have madara used genjutsu? 2 times, and what level of genjutsu were they? Both times were 3 tomoe genjutsu, once on Ay via a mokuton clone and the other on the kyuubi... So when has hashirama faced a genjutsu on the level of tsukoyami? NEVER,... The final question you need ti answer is... Does tye manga state ONLY a UCHIHA and SIBLING of the caster can break tsukoyami????
2. You say hashirama broke edo tensei therefore he cab break tsukoyami... Fail again genjutsu controls the mind edo tensei controls the soul mind and soul are not the same...
3. You say itachi's genjutsu couldn't free him of edo tensei well thats true for that circumstances because kabuto "Mastered " edo tensei being able to bring people back at 100% and even past their primes while orochimaru only brought them back close to their primes, thats a huge difference between edo tensei caster, also madara would have never been able to be free had itachi not took control of kabuto and saved the ninja world, kabuto would have taken away madara's personality had he tried and negated the possibility of him performing the seals but itachi saved the day so... Anyway KA was itachi's genjutsu, it was given ti him just like ms and. Kamui was given to kakashi so stay mad and anyway itachi rewrote what ka was used for he manipulated it to only counter his eyes...
