HTT will pull ahead unless you are in a situation where your regen is so high that the extra mana being burned is irrelevant. Also, AG requires the raid to be stacked and pretty much requires you to be able to be stationary and turret for its' duration to get the most out of it, so it would be terrible on fights like H Lei Shen, etc.
