When I directly compare the two of them, Ghaliyah al Majd leans more spicy-gourmand'ish with no funk at all in the musk while HM Royal Ghaliyah is more smokey and "heavy" with such an amazing vintage base to it. When I smell Royal directly from the dipstick, I can get a bit of that "meaty" musk funk (not in a bad way), which may be a result of the quantity of musk added, but once it is on the skin, that aspect is gone immediately. Also, the dry down for Royal is super addictive and lasts and lasts. I went back for more of both of them, if that says anything...
