whichever one you like the best
some people like the Lindt truffle type stuff, or See's Candy, some go for the dark stuff, which if it is good, is really good. Hershey, MFers, turned their own stuff to utter crap, and try to squeeze as many out as they can. My buddy gave me a truffle he got at some place in Rome as I recall, outstanding.
There was an old lady my grandmother knew when I was a kid that made little chocolates that were pretty good. Dark on the outside, fruit and nuts on the inside, depending on what was in season.
I like a lot of stuff these folks make, California company originally. I guess you like what you grow up with, good chocolate, not too pricey. I had a whitman's sampler that was so bad I threw it away last Christmas
