I usually get the regular over the double stuffed, because I do make my own double stuffed. This results in me having one cookie with the idea cream ratio, and two cookie shells to nom on with no cream. I can't imagine discarding the creamless half.
@Lionwarrior17 I feel the same way with Reese's. The normal ones are the perfect ratio and, when they go with the bigger ones or the event shapes, it fucks up that ratio.
