Craig, I place the Myers Dark on a lesser tier than the Goslings Black Seal or the Coruba Dark. The Myers has an upfront smell of ethanol which is born out in the taste. Sure there is a touch of molasses but, as a sipper it flunks. It is a backup rum for any drink that needs a Jamaican dark rum. Like you, I always go for the Coruba. With the Myers, it is hard for me to find any flavors through the hard ethanol taste.
The Coruba has that bold molasses nose which is definitely present in its taste. Coruba has a better burn on the tongue, too. There are hints of plum and prune. Behind those flavors, lies the molasses. Of course not a gentle sipper. But, I believe it is a better candidate than Myers for that guest which likes a rum and coke.
The Goslings Black Seal has such a laid-back nose for a rum with such a bold taste. It has a slight molasses and toffee smell. The taste is all molasses, though. I do not believe that it would pass as one of the other two rums in a well crafted drink. But, if one were doing a changeup with their Mai Tai, for instance, the Gosling would really lend itself to that purpose. Once again, not a sipper. Like the Coruba, it doesn't take much to make it a nice drink.
