Similar to the Oreo vs. Chips Ahoy! showdown, at 2:30pm 16 cookies of each variety were placed on plates in a central location in our department, and an email was sent out announcing that cookies were available. Because Oreos and Hydrox look so similar, the e-mail stated that both were available.
My thought going into this showdown was that Hydrox would win based on the novelty factor, or at least there would be a tie as people took one of each to compare.
At 2:55pm there were 11 Hydrox cookies left while Oreos had a slight lead with only 10 left.
From 3:00pm to 4:00pm, most of the cookie consuming members of the department were in a meeting, and by the time I had emerged, there were 4 Hydrox cookies left while the Oreo plate was empty.
To be honest, I was a little shocked by the outcome and how quickly it was decided, but my colleagues have spoken, and they preferred Oreos.
