On another level

[Sasori]

Tobirama and Hashirama must have been on another level to resist edo tensei while he Biju edo tensei couldn't so they must be strong of course. what so you think ?

It's their incredible will power.

 

[RaitonOniKairRasengan]

Hashirama was the strongest from the beginning of the manga to the time he was brought back as an edo, besides edo madara and juubito.

 

[Corgi]

When did Tobirama resist ET?

 

[Gagster]

What Biju edo-tensei? They can't die.

 

[Styles]

When did Tobirama resist ET?

He didn't only Hashi did

 

[Its sasukebase]

well the five tail jin did resits obito even with the chakra rods in him and tobirama never resisted edo

 

[Drackos]

Only Hashirama resisted Edo Tensei's restraints. And I believe the bijuu Obito used couldn't be used to their full power (using Six Paths jutsu along with their bijuu powers) as he either didn't have the chakra to control them or he just didn't have the strength at all to manage it.
