Kanna UB40 vs ET2: experiences and differences?

Has anyone here tried both UB40 and ET2 and could share their experience with each one?

I’d be particularly interested in:

a. How would you describe the effects of each one subjectively?

b. Which one feels more stimulating, calming, euphoric, anxiolytic, social, etc.?

c. How do the two differ in terms of the overall “character” of the experience?

d. If you’ve tried both, which one do you personally prefer and why?

I’m also curious about the pharmacological side of the difference. For example, differences in the alkaloid profiles, especially mesembrine vs. mesembrenone / Δ7-mesembrenone, and whether those differences actually seem to translate into noticeably different effects.

I’ve seen claims that ET2 is more stimulating/energizing while UB40 is somewhat more balanced or relaxing, but I’d really like to hear from people who have actually tried both.

So if you have experience with both UB40 and ET2, what would you say is the main difference?

Thanks!
