Hi aj and welcome.
Many arabian houses sell knockoff designer fragrances in oil form. Especially in the earlier years their customers were reluctant to use alcohol based fragrances for religious reasons or out of habit. Are they of inferior quality? Hard to say, but in the end they are knockoffs, so it may provide some ethical problems. Why did they smell so good? Maybe because they lack the properties of fast evaporating alcohol, maybe because of the higher concentration, maybe because they were knockoffs of good fragrances.
They are a big company with some excellent stuff, but they usually price themselves much higher than they are willing to go for. At least that's the case in the Gulf area.
Hope it helps.
