I think this post on the SA forums sums up quite nicely everything there is to say about the Dominions AI:

The AI is not a highlight. It's enough to keep someone like me who doesn't have consistently available time for multiplayer entertained, but there are quite a few strategic nuances that the AI doesn't really understand and can't effectively defend against. The AI tends to be better at massing troops than most humans, though, because most humans don't have the patience to collect troops from every territory.

If you are a king of strategy games and want to be challenged, you will need to play humans eventually. If you just like stomping on thousands of human infantry with your unstoppable horde of angels/devils/zombie gods/zombie woolly mammoths/tarrasques/things man was not meant to see the AI can keep you entertained for years.
