I've compared elite cuts from both the Queen Mother, Zamaldelica and Zamal GN Collection. Zamal has the high, Queen Mother the terpenes and Zamaldelica the raw potency.
I've tried the Zamaldelica clone from Eddie (25%THC), passed to ACE for producing seeds, and found them potent and with nice citrus terpenes yet a bit muddy and couchlocking too. Smoked similar to strong Jack Herer, Mango Haze or SSH. Not sure about current stocks tho.
Queen Mother is complex in both terpene profile and high... some people get often spaced out if they smoke too much. So it's not a super clean sativa but is a nice and unique plant for sure. I've tried some energetic phenos and also some others more trippy or stupifying in effect.
As always, it's a matter of finding the right pheno for each one. One plant doesn't affect everyone the same either.
