Thank you for the detailed description. Very well explained.In all honesty I was not impressed with Guallam no1 and sold my bottle with in a couple of days of receiving it and I have only tried a tiny amount of Kinam Rouge once, so I can't comment much on either of those. As a caveat - I do not enjoy any type of crassna fruitiness or even that rings of a basic crassna to my brain. For some reason I find it personally offensive
As an aside - Vietamense oud seems to rank pretty low for me overall as I also quite disliked high grade Vietnamese from Taha like - hansei, wanmei, Vietnan Spec K. The hansei/wanmei to my nose were a combination of dirt, bandaids, leather, and fruits, where as VSK was leather, bandaids, and fruit.
On the flipside - Royal guallam and Nha Trang LTD are both amazing and I feel like Guallam Kilam will be on on the level of Royal guallam but not Nha Trang LTD(of course.) Still need a bit more time with Guallam Kilam to dive in deeper but really enjoying it so far.
No fruitiness of VSK and doesn't have the sharp opening of NTLTD, it is much quieter and more mellow oil.
It is less fruity and more complex than NTU but also lacks the sharp opening that both NTLTD and NTU have.
I would say it does indeed have the green and vanillin overtones, alongside the other aspects that I mentioned, but it really resonates with more with many of the Japanese "kyara" incense sticks and less with my experiences of heating green/whine kynam, so I would say to leans more on the black or darker side of things due to the musk and sweet molasses overtones.
