My vote for Best Candy: Recess Pieces. Indeed, the Peanut Butter Cups are better, however as mentioned in the video they have a tendency to get all melt and sometimes the cup-wrapper gets stuck and starts peeling off chocolate along the side of the cup...they can just be a bit too messy. Recess Pieces, on the other hand, keep as well as M&M's, STILL give you mouthfuls of peanut butter and chocolate, and like M&M's they also have a nice crunchy candy shell. :3
My vote for Worst Candy: Tie between Candy Corn and the Giant Peanut Marshmallow. Seriously, those peanuts make better doorstops than treats.
