Is there a difference between MDA the color, best i had long SR ago was a tanish color.. white seems to be all i see now

I dont know why but the person that had sold it on the SR a long time ago was so high rated and the product was amazing it had a crazy chemical wash smell to it but was so great an experience, i just am not sure about the white MDA that i see, anyone had any good vendors.. I just feel like MDA is way better IMO than MDMA.. i dont get why molly got so big and is all the craze when MDA is so much better... again IMO...
