Why is Condition Overload considered preferable to Primed Pressure Point on so many builds?

Assuming that I understand the way the mod works correctly, it gives +80% additive base damage per unique status effect currently on the target. That being the case, it will be inferior to a maxed Primed Pressure Point until three different status effects have been applied. Why does CO seem to be preferred when it just seems to be not as effective unless you're also running a status primer of some kind?
