This is my personal taste test.
I am a chocolate fan. Now for the heresy, I don’t particularly like Godiva. I do like plain old milk chocolate. I have tried all of the chocolate I have seen, ever! Ghirardelli Chocolate is excellent but I have not found it in the bite size pieces. So my simple, unscientific test is base purely on my findings. Given a choice, my wife, my 13 year old grandson, my 7 year old granddaughter and my 5 year old grandson all prefer the Hershey Nugget over the Bliss and Dove and so do I. No science, just taste! Once again, more expensive is not always better or better for you.
One Hershey Nugget 10.25 grams; 50 calories $0.41/oz
One Dove Promise 8 grams; 26.25 calories $0.61/oz
One Bliss 7.1 grams; 35 calories $0.62/oz
