I found the Gold to be not as sweet as the Blue but it had a very big citrus back bone. The Blue seemed to have flavor that were much more rounded and a thicker mouth feel. The Gold had more hey like components and it was a bit thin. The Gold is a nice flake but I did not cellar it because I enjoy the Blue much more and the Gold was similar to my other morning flakes like Dunhill Flake, Wessex gold and F&T Cut Virginia Plug but not as tasty as those three. Add into the fact it is not a cheap flake, made it was a no go for my cellar. I think it is worth getting one tin to see if it is something you might enjoy, all of our tastes are so different that you might find flavors that I don't.
If you are looking for something sweet like the Blue, the Brigham Klondike Gold is a great flake, it has been aged in the tins and you can really taste that fact. I think the Blue with some age will be as good as the Klondike Gold in a few years.
