It's likely that:

Shinobi unite against God-tiers. Biju-tiers will fight the remnant God-tiers. Kage-tiers will fight the remnant Biju-tiers.

Anything below Kage can't really bother, since they would likely be fodder in the ensuing fights.

People like Hagoromo and Hamura would likely team up, but people like Madara and Obito would likely side with someone like Kaguya to even the odds enough to survive the aftermath. Even if such combinations are somewhat out-of-character, against fairly strongly united fronts (friends > clans > villages ) they would pretty much have to in order to stand a chance.

So i believe it comes down to whoever is best at surviving the initial onslaught and then defeating the remains, which is why i came back to Zetsu. And though he may not fight at kage-level, his hiding and infiltration power was beyond even Kage abilities to detect.
