Both of them are antagonists that more or less act like heralds of divine power and have been identified as leaders of their organizations. Both have also tried to seize an asset of the main characters from their stories but end up becoming their allies after their initial defeat to them. So this battle would come down to God'a power against the Sage of the Six Paths' because both Fiamma and Nagato have an arsenal of abilities to use against one another.
