inb4 mokuton supression. based on the info we have so far from yamato and oro, hashirama could make the full bijuus into pets but jins didnt exist. yagura and bee were brand new types of jins, ones that could perfectly either turn off their power or use bijuudama with correct timing. plus it merges the powers of both the host and bijuu. so its way different to 1 vs 1. how does hashirama tie up the man who was keeping pace with 4th raikage in their fights, and with minato? how does he supress hachibi when bee is the one controlling the tentacles? nothing to supress. in his fight with A, he showed he could make the cloak/tentacles without V2. mokuton turns off the cloak if it connects. only if it connects. ginkaku can fire off katons from the fan or raiton, to aid bee's long range whirlwind and bijuudama. in V2, he retains speed and power. and if they get entangled, bee just turns it off.
even hashi with his little feats cant take all of them at once. he most likely knows nothing about the rikudo weapons. so one touch from the rope and its over. clones get destroyed by lariat or raiton swords. wood vs raiton = yeah i think raiton wins. kin and gin defeated hashiramas brother and 2nd raikage so we know they are especially insanely strong with huge chakra levels. however yamatos shown suiton to put out the bashoshen katon. as for pollen, hachibi can wake bee up like with genjutsu
