OP talks about BM Naruto, not BSM Naruto. Not as if it changes a thing anyway since his boast most likely only happen on his body itself, not on the chakra cloak he uses when entering said modeI'm glad Hashirama isn't here, that dude just makes all versus threads boring.
I give it to team 2 high diff. BSM Naruto is truly something dangerous; increased physicals/ninjutsu while increasing threat perception coupled with bijuudamas and immense speed.
Although, Bee is a bit of a weak link in this battle.
