I can imagine there would be disagreements mostly.
Why is that, then? When they’re in different cosmologies, what often happens is you find some gods exist in the other system under a different name. Then there’s no reason to disagree.
I’ve been in some “meetings” with Sumerian Gods and the Infernal Demons, Lucifer and some of the Greek Gods, there’s agreements and disagreements, it’s normal per individual. I’ve found Zeus tends to butt heads with Paimon but nothing too serious, but I never digged into why.
