I suppose it all depends on which one is bigger overall, the brethren moon or xenomorph prime?

Since the size of the planet (or planetoid) determines the victor.

Though considering that the brethren moon is technically undead, it may have a slightly larger chance of victory because it doesn't have to worry about being killed
