Buckwheat does take a little adjusting of your expectations. Definitely not the worst tasting honey, even the first time I tried it. I keep some around, but then, I like dark molasses also. Our bees work Aster and goldenrod together, along with whatever else is around that time of year. Haven't tried to extract any of it, as I can't get past the smell. Also, I don't particularly want honey that crystallizes (so far, never a problem with spring/summer honey, even after 3 years). I'm thinking of planting as a cover crop and late honey source (timing for late august). How large an area would be needed to be useful?
