What is Liquid Brun a dupe of?
Parfums de Marly Althaïr is the reference for French Avenue Liquid Brun, and I'd give the scent similarity 94%, or 9.4 out of 10. If Althaïr is the fragrance you're trying to get close to, Liquid Brun would be high on my list.
That's a scent rating. I'd make a separate decision about which bottle I prefer to wear and whether the current price difference makes switching worthwhile.
Why Althaïr is the obvious comparison
The French Avenue UK listing puts cinnamon, bergamot, cardamom and orange blossom in the opening, then Bourbon vanilla and elemi. Praline, musk, ambroxan and guaiac wood are listed in the base. It's a warm vanilla idea with spice, sweetness and wood around it.
Parfums de Marly's current Althaïr description highlights vanilla, praline and orange blossom. Its pyramid also includes cinnamon, cardamom, elemi and guaiac wood. With that much overlap, the comparison makes sense before you even get to the price.
Would I buy Liquid Brun instead?
At 94%, I'd give Liquid Brun serious consideration if I wanted this style and its current offer suited my budget. I'd pay attention to the sweetness in the opening and how the vanilla settles after a while. A fragrance can be very close to its reference and still make you prefer one version.
My 94% rating is an overall scent comparison. If you're sampling them yourself, pay attention to the balance between vanilla, sweetness and the warmer spices. Small differences can matter a lot when this is a fragrance you plan to wear often, even when the overall resemblance is strong.
Where does Vanilla Dunes fit?
Khadlaj Island Vanilla Dunes is another Althaïr alternative we've covered. This score belongs to Liquid Brun. I'd compare the two alternatives if you can find samples, instead of assuming they'll feel interchangeable because they share a reference.
