There's nothing better on the mass-market than a Reese's Peanut Butter Cup, except for Reese's Peanut Butter Cups in the shape of (half) eyeballs in honor of Halloween! I'll make one complaint, although a subjective one. I prefer my Peanut Butter Cup to be heavy on the peanut butter, light on the chocolate. In this iteration, there is a higher ratio of chocolate to peanut butter because of the constraints of the shape. For some, this could be nirvana, but not for me. I'll still eat all of them with gusto.
Score: 4 (1 point deducted for chocolate-peanut butter ratio)
