There is no comparison (in my 'cellar' or experience) of Dunhill's Nightcap to its other Lat offerings. I don't have any others, and I haven't tried any others. I went to Nightcap and worked my way around the lat blends of other houses. I've read many a glowing compliment for just about all of Dunhill's blends, so I would imagine that it's their quality and precision that first strikes the initiate. If it was EMP you tried first, that's probably your favorite, and so on.
Thank goodness not all latakia blends are homogenized. Eh, blenders?
