I did mdma first then meph sometime after, and I generally agree. i'll talk more about my meph experience specifically.
MDMA (pure molly): magical, lots of euphoria and lots of empathy, more emotional and connected. senses are increased, slight visuals. feelings of contentment. lasts a good 5 hours.
i take my mdma capsule, maybe one redose and i'm good through the night. usually pretty happy/afterglowing in the morning and following day
meph:
more energetic, fairly fast acting, but short lived. i feel a little euphoria, but more energy than happiness. no empathy or "magic". it does make me feel good, but not as clean as mdma. after about an hour i am compelled to redose, and i continue through the cycle of coming up, down, and redosing through the night. its easy to binge on this.
meph was kind of coke-y to me, not as intense or stimulating obviously. i think meph goes along well with drinking as well. i cant do alcohol with mdma, but it worked well with meph.
comedown: kind of harsh, i think it was because of the redosing throughout the night. had a lot of depression right after the comedown, but was okay in a day or two. no afterglow as such.
