Erinmore is one of my favorites, especially in the summer. It will have an off-putting tin aroma, but that does not translate into the taste of the smoke. It has a very fruity-like flavor. I compare it to Juicy Fruit Chewing gum. But, it is a very balanced flavor with the tobacco, IMO.
But, I hate the ready rubbed version of Erinmore . It has a different flavor profile, for some strange reason.
I generally prefer the flake versions, even if I rub them out myself. They seem to age better, and have better flavor. The ready rubbed versions of the ones that I have tried just seem to lack complexity... or, the topping/casing just doesn't shine through as well. The Vanilla Flake verses the ready rubbed Vanilla Flake are like two totally different blends, IMO.
Whether I cube cut, rub it out, wad it, or fold and stuff, the flake versions just give you more options, along with better aging characteristics, and overall flavor. YMMV But, some really like the ready rubbed versions, so it's all a matter of opinion.
