neither one of these are going to be some kind of practical everyday fragrance or something to "get the ladies (or guys)". These would be something to buy for your own enjoyment if you do in fact find them enjoyable. Buy whichever one brings you the most.
I bought Chergui about a year ago. I wear it mostly in the fall and winter months upon occasion. I don't find it powdery, maybe a slight hint with the incense. I find it to be more or less a combination of dry honey, hay, tobacco and light woody/spicy. If you don't think LDDM is too gourmand, too powdery or too sweet I don't think you'll find Chergui to be those either.
