Hershey's Kissables are actually pretty good too.. I haven't had them enough to really determine if they are better than M&M's or not, but they seem really tasty.
But M&M's rock.
I'm not much of a chocolate candy person though. I love candy on its own, but not chocolate candies, not all that much. Me, I prefer a really good piece of chocolate or two or a handful, or squares off of a really good chocolate bar. Dark chocolate preferably, milk chocolate is too sweet and creamy. But I don't want 70 or 80% dark either, way too bitter. 60% is a happy medium for dark.
