Thanks, I compared the effects of the two and found nene has a little more uplifting mood, feeling happy. While moi was more activating, more energy. Although this only a theory of mine. The happy nature of the nene impressed me and I was hoping to find the chemical difference between the two, but you know how mysterious kava is.
Anecdotally, I've found Nene to be more sedating, and Moi to be more emotionally uplifting/euphoric, it's very interesting how subjective these effects tend to be between people!
