Coming from a background of mostly psychedelic use(LSD and Mushrooms mostly in the late 90's), I prefer MDA.
What I like about it is the depth of the "hallucinations"(more like being in a delirious dream state), the fact that it makes you feel goooooooddddddd and it is not as "heavy" as the classic psychedelics.
Honestly, to me all the MDx compounds are great. If I were out at a rave dancing or in a club I'd prefer MDMA though as it's a little bit "clearer headed" than MDA.
Too bad we currently don't have the option of actually knowing beyond a shadow of a doubt what is really in our pills.
