If I had to choose one, I'd pick MXE. It was very magical, uplifting, euphoric and clear minded. Well, the first dozen times anyway (plugged). I should have respected this one.
I couldn't put them in any order (different choices for different moods), but these are some notable ones.
25c-nbome - very fun and easy going, great mood, great buzz
MXE - Love this one! Although it seems to lose its magic quickly. Don't overdo it like I did!
MDAI - Very pleasant, great for combos or just relaxing
4-FA - Very fun and cognitively enhancing, not too fond of stims, but this one is great once in a while. Bit of empathy followed by easy stimulation and gradually into a mellow comedown, or "wind down" really
2C-E - Very intense and serious, but quite profound
Neutral...
4-HO-MET - A bit of trippy fun, but I found the body load or energy really quite pushy. It wasn't particuarly profound either. Not bad though
Ethylphenidate - That first bump.....heaven! But the compulsive redosing and, to a lesser extent, the comedown makes it quite difficult to be a favourite. If i manage to control myself with low, spaced out doses it is much more pleasant, but more functional than recreational.
DOI - more of a novelty and haven't had the 30-70 hour time frame to test further. Apart from the duration, very nice though.
Eh..
MAM-2201 - Don't enjoy the high that much, although it's interesting. Trippy and paranoid weed high. Quite addictive, I don't even want to do it sometimes and I will anyway. The buzz can be uncomfortable too. Will not be acquiring again
