I'm gonna guess that the ENFP is more of the mean and selfish control freak or cold and calculating bitch (no offense) because of their tertiary Te, while the ENTP is more of the charming, subtly manipulative type because of their tertiary Fe.
Ne will give an ENFP an idea, and they will express their idea in a forceful way due to Te, but according to their values because of Fi. For example, since ENFPs are not necessarily nice, they will likely dream up the most sadistic ideas for revenge on someone who wronged them.
Ne will give an ENTP an idea in a similar manner, which they will express in a more superficial charm sort of way because of their tertiary Fe, but they rationalize their desires better because of Ti.
Ti and Fe (at a lower profile) lead ENTPs to be more bouncy and airy in their expression of crazy Ne ideas, while the Fi, and Te (at a lower profile) would lead ENFPs to be more passionate, forceful, and values-oriented in their expression of crazy Ne ideas.
