I most definitely do. I have a few bottles of each. Green Label, IMO, resembles a good highland blend, very smooth without any distinctive notes, but very pleasing and absent the rough spots customary in lesser blends. Green is my fallback if I am short of Double Black or good Islay.

Double Black is very similar to Islay, quite peaty and with a distinctive earthy scent and taste. Wherever I find Double Black in Duty Free I buy what I can because it is my new favorite everyday tipple.

I like Scotch and have a decent collection but I am no expert so my descriptions are not great. My favorites generally are various Bowmore and Balvenie, mostly older ones and my all time preference is Port Ellen when I can find any, meaning I have only my diminishing stock since there is no more being produced.
