Huyana Capac is by far the best warlord at deity level. This has a lot to do with the fanatistic unique unit and unique building. But the industrious (new) and financial pairing is ridiculously useful, especially (and perhaps surprisingly) for cultural victories. Financial gives large early-game tech boost, and small late-game cultural boost (when you start producing culture instead of commerce). And industrious is absolutely invaluable in obtaining those high culture wonders (stonehenge, parthenon, sistine chapel, notre dame, taj mahal, etc.), and an equally valuable health wonder (hanging gardens).
