That is untrue. Armor Piercing is on the ignored damage type list (aka armor ignore) for almost every enemy. However, It is also on the damage multiplier list for two types of enemies, medium Grineer (x1.5) and light Infested (x0.5) This means it does 100% to majority of enemies.

Kunai on the other hand do Physics Impact damage, which people often misleadingly call amor ignoring damage. While Physics Impact is on the ignored damage type list for most enemies like AP, it is not for a few that AP is on. For a few enemies (Grineer Commander and Seeker for example), Physics Impact damage does reduced damage due to armor, while AP will do full damage. For all other enemies though, yes it does 'ignore armor'.

That being said, it's clear that Despair wins out. Light Infested are easily killed by many other weapons, and even if you choose to use Despair against them, they are generally weak enough that Despair can still quickly kill them even with damage reduction.
