I'm another fan of BWB's Honey Flue and Honey Flue Nut. To me, it tastes like I dipped my finger into a jar of really high quality dark honey, like the kind with the honeycomb in it! My other favorite is AVE's Flue Cured, it also has a nice, but different honey flavor.
My favorite caramels so far are BWB Dulce de Leche, and Want2Vape's RY4. The latter is much darker, kind of like a slightly burnt caramel taste, though I don't want anyone to think it tastes burnt - just a "toasty" kind of caramel...
