MDMA wins when you factor in duration and after effects.
I am almost embarrased to say that my first crack rush was at least as euphoric, but the duration sucked and the results overall were catastrophic, it is the WORST drug.
Freebased coke seemed to make me euphoric as well, but again, the duration sucks and the highs get less and less and the crash gets worse and worse. Again, something to avoid altogether. Not nearly the benefits of MDMA.
I personally do not consider MDMA to be as hard as suggested, simply because I do not define hardness as a function of physical damage, but rather, I include the potential for addiction. I have found MDMA to be non addictive, whereas coke was a motherfucker to kick. For me, coke is WAY harder in every regard. Which is why I avoid it, period.
MDMA is fantastic.
