I love Lakelands and to me they're very different.
Brown Flake Scented has maple and tonquin flavoring, I think, while Ennerdale has cherry, almond and rose (or something like that). With the Brown Flake, I get lots of mild, sweet maple/vanilla flavors, while Ennerdale just tastes weird and fruity, with some roses mixed in. I love it, but it's just plain weird. The tobaccos in Ennerdale are brighter, too, so it's more like a bright VA flake than is the Brown Flake Scented. Of all the scented Lakelands, I think Brown Flake Scented is probably the least weird. Almost all the others have flower essences or musk, so the maple and tonquin (vanilla-type flavor) in BBS is fairly tame by comparison.
