Poseidon because he has control over all realms, he can cause major earthquakes, obviously control water and there is water in the air, and storms. Hades may have the dead, but he cant use spirits from asphodel or Elysium, and most spirits from the field are close to dying a second time, so his numbers are lowered. Poseidon has all the Naids, Potami/mids, and Nereids if he bargains with Nereus. Then he has all his immortal children, along with every creature of the sea, most of which haven't been discovered, along with  every hippocampus, Pegasus and sea monster.He also has the Cyclopsi. and way more gods aligned with him than Zeus or Hades.

Zeus despite everything, is  literally the weakest of the big three, except the master bolt, which Poseidon can duplicate, since he has Cyclopsi and peanut butter!Storms don't work in the underworld or underwater. I'm sure there is some way (that only Rick Riordan could think of) to give Poseidon some defense  against electrocution if so Zeus is pretty much out of the battle.

Athena might side with Zeus, but Annabeth would go all "Mom, why do hate me" teenager crap, and they would have the ultimate stormy eyed mother-daughter staring contest, and the fight would be long over by the time one of them backed down.

Ares / Mars would either be bought to a side or go neutral, Aphrodite/Venus would turn it into a twilightish love story, and Eros would be at home making love to Psyche.

I don't thing Zeus would be able to harness the ever swift wing gods again( so mad there was no description of Eurus) so they're free to side with whomever.

Persephone might get mommy to side with Hades, but she'll probably just stay back because     A.She loathes Hades B.She is totally done with Zeus"s manipulation C.She loathes Hades.

Hades has the sword of course, but Styx would seek him for breaking his oath, so I'm just going to count that out. After this, Hades and Poseidon are very evenly matched, but Poseidon might have so copy-bolts, the infinitely strong cyclopsi, a hundred handed one, and a vast army of water spirits, plus with Zeus out of the way, he can't be electrocuted( his biggest weakness), plus corpses don't go with water, so a chunk of Hades army is removed.

In conclusion, Poseidon for the win!
