Scenario one: Naruto low diff.
Scenario two: Naruto mid diff.
Bijuudama isn't GG as that isn't an omnidirectional attack so if Naruto surrounds the Hachibi with clones, Bee can't defend from the sides or back if he attempts to attack what is in front of him. Naruto should be able to easily outmanoeuvre Bee. FRS did quite a bit of damage to Kurama, making it scream in pain. Bee suffers a much worse fate as the Hachibi is much less durable. With so many clones surrounding him and Bee being immobile, Bee gets wrecked pretty badly. Hachibi whirlwind doesn't do much damage to Naruto as his cloak already protected him from it.
Furthermore, Naruto should be fast enough to dodge TBB as they've been shown to be as fast as FRS, YMs, whereas Naruto can easily react to V2 Ay who is much faster than 3rd Raikage who was able to dodge FRS. The AoE may catch Naruto but with Naruto's shunshin, he can avoid being in the epicentre and end up not taking much damage. Bee's tentacles didn't suffer much damage from the AoE of the TBB blast from the Hachibi so I doubt an indirect hit from a TBB would do much to Naruto considering that Naruto's cloak is more durable than the Hachibi's tentacles.
