I have now tried the Coke Oreo Zero Sugar soda and the Coca-Cola Oreos. They are entirely Fine and not groundbreaking.
The soda is fine as far as fake sugar pop goes. Not really much of an Oreo taste but it's kinda there. I can see how it would be off-putting to some. If you don't like Coke Zero you won't like this, of course.
The Oreos are strongly scented of Coca-Cola. They are double stuffed, which I feel was a good choice as it lends a cream soda note. The pop rocks are present but not overwhelming. I like the red cookie with the branded stamping.
I will not be seeking another bottle (we split one at work). I may purchase more Coke-scented Oreos, but I think the original is better there.
