I've been dealing with Oud oil for years now, and it seems to me that there's a slight oversight in your comparing between what Oriscent and what Montale is selling.
"Oud" is a term that is used in the Arab world to refer to a natural essential oil that comes from the Aquilaria tree. The different species of Aquilaria grow in different regions in the Far East - although they are all seriously endangered. The essential oil that comes from the fungus-infected trunks of this tree is the costliest aromatic substance on the face of the earth.
It is precisely this oil that you will find on Oriscent's website - 100% pure, unadulterated Agarwood Oil - and some of them are of the grades that are used by the Royal Families of the Gulf and Middle Eastern countries (esp the Oud Royale and Borneo 3000).
What Montale offers, on the other hand, is a synthetic imitation of agarwood oil. And many French perfumeries (like Montale) produce synthetics that are meant to "capture" the fragrance of a precious substance. You seem to have picked up on this, since you say the Montale line will appeal to anybody that likes the "Oud effect". That is exactly what it is, in reality, an "Oud effect" that does not posses even a single drop of pure Agarwood Oil in it.
I am sorry if you already knew all of this. To me, it just seemed a little out of place to compare the real thing to synthetic imitations - and to say the imitation is going to win "hands down" when compared to the real thing.
I have been wearing the Oriscent Ouds for years now, and there is nothing so spellbinding, so spiritually uplifting as their 100% pure Oud oils.
