That's not quite how drugs work. I've done many of them. They each have an effect that is distinct and separate from their risk profile and addiction properties.
Cocaine feels very different to MDMA and heroin is different still.
MDMAs effect is one of filling your brain and body with love, bliss, sexuality and euphoria. Every sense you have is now coloured with absolute pleasure.
That's a very specific feeling. Comparing the effects of drugs in a way that judges their relative value is usually not helpful.
For example MDMA isn't hallucination inducing like LSD.
Other drugs transport your consciousness to completely alien experiences of space and time.
MDMA isn't like that. You're still you and your experiences, experienced through a new lense of pleasure.
There is always overlap, the palette of chemicals to alter in your brain is limited and these drugs alter often the same ones in different ways.
It isn't the drug that is important, but the experience. That's subjective and as tricky as judging the beauty of art.
Cocaine for example is fun. It feels good. You're energised, uninhibited, and combined with alcohol products enhanced euphoria. But if cocaine is Jackson Pollock then MDMA is Georgia O'Keeffe.
