This isn't meant as a contrast to your appreciation thread, just sharing my own perspective as an Ne type. Often Ni types seem to me to state the obvious truth (or lack thereof) in a convoluted way, for a purpose, as not to reach an objective point in their understanding but to gain grounds for possibilities and new perspectives for their own interests. They build their understanding of them like webs reaching in different directions, so they can feel more confident in whatever they're talking about. So there's a + and a -. Usually I find their topics pretty clear and simple, but I can see how it refreshes their mind and the minds of any sensing type. It brings raw sources into fluctuation so it has a
true originality unlike Ne (like all introverted functions.) It even gets me thinking.
Ime Ne is more about obtaining the hidden truth/essence in philosophies and other contexts, without requiring a literal knowledge (as all extroverted functions do), so I find it much more useful and interesting. Really it builds from its own philosophy for where truth can
best be appreciated (again a trait of extroversion.) Ne isn't a typically insightful function because it's not about localizing our knowledge, but rather taking our knowledge to a greater level, aiming for the original idea rather than starting with it. Ni doesn't understand this process of thinking very well at all, in fact this intuition to them is unrealistic because it doesn't really answer their own problems. Of course I'm sure Ni valuers think Ne is about localizing and Ni is about reaching a new level, as I'm sure it does for them in an opposite way, but the result is very local for me and the conclusions they reach are obvious, albeit useful in general.
Overall point: Ni works for Ni quadras, Ne works better for Ne quadras. So let my natural criticism be momentary and your appreciation further.
Here are some pictures:
