My Mom makes gourmet chocolates as a business. She has a 2nd kitchen in the house that's totally dedicated to this enterprise and she's been doing it at least on some scale for my entire life. The stuff she makes is such high quality and so good that I've become a snob and I either don't like most mass-produced chocolate bars or I can only take them in small quantities. All that being said, I can still gorge on fun-size Snickers like nobody's business. Based on my unmatched wisdom and expertise, I would say that hands down, that's the best chocolate bar, and it's not even close. Reese's were my favorite as a kid, FWIW.
