Hashirama used Deep Forest Emergence, which is his signature move. Due to having half of his chakra reserves, it's obvious Hashirama couldn't uses other stronger techniques of the Wood Release. And for Tobirama not using the FTG, it's the same way. It didn't matter much as Tobirama's signature fighting style was using water release. The fact that you make Hashirama have to resort to using his top jutsu to defeat Hiruzen is proof enough that he is a formidable opponent.
