Reese's Peanut Butter Cups - a dispute

So two of my coworkers were having a deep and very important conversation this afternoon, about affordable housing. I had just had a difficult meeting about the topic at work, and was decompressing with my coworkers. Incidentally, I had also just relaxed by eating a couple reese's peanut butter cups. Making a comment about the chocolate, the conversation followed like this:

Coworker A: "Ahhhhh, the little ones?"
Me: "No way, the full size originals."
A: "I've always liked the little ones better."
Me: "No, I prefer the bigger ones."
Coworker J: "Me too, I've always liked the big ones better."
A, to me: "Why is that KG?"
Me: "Better ratio."
A: "But the little onces have a better ratio, more chocolate than peanut butter.
Me: I know, the big ones have a better ratio of of peanut butter to chocolate. Mmmmm, peanut butter goodness."
J: "Wait, I think there's more peanut butter in the little ones, that's why I like the big ones."
Me: "No, there can't be. There's more edge on the little ones, and more of the thin flat on the big ones. It's kinda like brownies - the edge pieces and the middle pieces."

A chuckle from the hallway.....we look up.

Client: "Wow, you guys are really busy, aren't you?"

Aack! Such a Seinfield moment!

But really, what do you think? Is there a higher ratio of chocolate to peanut butter in the little ones, and higher ratio of peanut butter to chocolate in the bigger ones? Or is it vice versa?
