Four years ago, someone in the NoStupidQuestions subreddit asked if the bars were different. While one user wrote, "They're completely identical. It's just an advertising campaign," another responded, "Wrong. Left Twix is clearly superior with us smooth chocolate flowed over the creamy caramel and crunchy cookie."

We hope you enjoyed that debate as much as we did.

Now, let's get down to business. We were intrigued by the concept of there being a difference, so we did some research. According to Recipe Maker, "In the right Twix factory, caramel flows on the cookie, while in the left Twix factory, caramel cascades onto the cookie. There’s a distinct difference in the coating process."

If you're still wary of the truth, the publication continued, "The distinction [between the two] can be found on the label, as the right Twix is cloaked in chocolate with cascaded caramel, and the left side is enrobed in chocolate with drizzled caramel."

Though neither manufacturer can deny the similarities between the left and right Twix, the campaign is an ongoing discourse that's left consumers in disarray.
