NeFi - Discoverer Advocate
The theme for ENFPs is inspiration, both of themselves and others. Talents lie in grasping profound significance, revealing truths, and motivating others. Very perceptive of others' hidden motives and purposes. Interested in everything about individuals and their stories as long as they are genuine. Contagious enthusiasm for "causes" that further good and develop latent potential and the same zeal for disclosing dishonesty and inauthenticity. Frequently moved to enthusiastically communicate their "message."
Ne - Interpreting situations and relationships; picking up meanings and interconnections; being drawn to change "what is" for "what could possibly be"; noticing what is not said and threads of meaning emerging across multiple contexts. Noticing the possible meanings of what you might wear: "Wearing this might communicate…"
Fi - Valuing; considering importance and worth; reviewing for incongruity; evaluating something based on the truths on which it is based; clarifying values to achieve accord; deciding if something is of significance and worth standing up for. Evaluating whether you like an outfit or not: "This outfit suits me and feels right."
Te - Segmenting; organizing for efficiency; systematizing; applying logic; structuring; checking for consequences; monitoring for standards or specifications being met; setting boundaries, guidelines, and parameters; deciding if something is working or not. Sorting out different colors and styles; thinking about the consequences, as in "Since I have to stand all day…"
Si - Reviewing past experiences; "what is" evoking "what was"; seeking detailed information and links to what is known; recalling stored impressions; accumulating data; recognizing the way things have always been. Remembering the last time you wore a particular item or the last time you were at a similar event—maybe even remembering how you felt then.
NeTi - Explorer Inventor
The theme for ENTPs is inventing, finding ingenious solutions to people and technical problems. Talents lie in developing ideas into functional and innovative applications that are the first of their kind. Thrive on finding new ways to use theories to make systems more efficient and people better off. Hunger for new projects. Have faith in their ability to instantly come up with new approaches that will work. Engineers of human relationships and systems as well as in the more scientific and technological domains.
Ne - (same)
Ti - Analyzing; categorizing; evaluating according to principles and whether something fits the framework or model; figuring out the principles on which something works; checking for inconsistencies; clarifying definitions to get more precision. Analyzing your options using principles like comfort or "Red is a power color."
Fe - Connecting; considering others and the group-organizing to meet their needs and honor their values and feelings; maintaining societal, organizational, or group values; adjusting to and accommodating others; deciding if something is appropriate or acceptable to others. Considering what would be appropriate for the situation: "One should or shouldn't wear…" or "People will think…"

Clearly ENFP has a more "fluffy" feel than the more "technical" ENTP. The trick is distinguishing a particularly sciencey ENFP from a particularly humanistic ENTP... what you have to identify is whether you seek more purity in your T or F function - ENFPs are more concerned about perfecting their ethical/feeling values, and figuring out what is right and wrong, while we really don't care much if something is logically perfect as long as it's effective in the external world. ENTPs are more concerned about perfecting their logical systems, and figuring out what is correct and incorrect, while they really don't care much if something is perfect in terms of feeling impact as long as it's effective in the external world. We'll spend more time ruminating on those things, accordingly.
I've also heard the comparison that ENTPs are more charismatic while ENFPs are more charming, which I find surprisingly accurate.
