the one millions vs there ancetors batman/superman

Kal-kent and Batman one million  vs Current superman sa levels  and batman at his best.
Both teams are blood lusted and  the Present versions ie, supes and batman have 7 months of prep before the fight starts. how dose this go down?

I say with prep the ancestors have a chance of  coming out on top . Since the future bats and kal kent are heading in to this with out prep as an advantage .
