- Itachi does not have formidable strength, so his spirit class in YYH would be something like D class. Hiei started out as a B class demon, so his raw power is far more formidable. Even if Itachi could see Hiei's every movement, Itachi likely could not match speeds.

 - This might really come down to Amaterasu through Susanoo vs. Dragon of the Darkness Flame. Also, note that the spirit classes in YYH can be measured with physical strength, but there isn't really a way to measure chakra with any of YYH energy types.
