somewhat in this order i guess at the moment, based on my experiences:
-LSD (love the trip, I get synesthesia, and the afterglow is amazing for me quite often)
-Sativa, well any predominantly sativa strain or Hashish (some of my most profound trips ever, usually oral)
-Psilocybin (afterwards feel generally grounded somehow)
-Alcohol (don't like getting drunk, just a few drinks==great buzz and conversation)
-on occasion in the correct setting, if i don't do it too often, the 2-minute nicotine trance
Mescaline could easily be on this list if I have a chance to try it again, I loved my threshold experience. As for the Shulgin Phenylethylamines, in my two experiences fun and visual, but I tend to trust the classic psychedelics more as we know of their long term side effects and I have more of what I actually want out of a trip with them. Haven't tried Ayahuasca so can't say how this list will look after I have tried it either.
Nice one!
