(Tacitus)Whose the best?

Out of all the accounts, I believe that Adam's(Herodotus's) accounts were the best for a historian, just because he goes into a lot of detail about the events that happen, their causes and effects and covers all of the different civilizations as well as his own. Although, he often explains the causes of events and history as mythical/mystical. For example, when Rome decides to help Africa defeat Egypt, Adam describes that this decision was made because the archangel Gabriel came down and told him that it was God's will for him to intervene.
