When it comes to Coca-Cola products, people tend to be die-hard fans. While Diet Coke has been a leading sugar-free soft drink since it was first released in 1982, it came to light that young adult males shied away from this beverage -- identifying it as a woman's drink. The company's answer to that predicament came in 2005 -- in the form of a shiny black can -- with the super-successful release of Coca-Cola Zero.

While Diet Coke was created with its own flavour profile and not as a sugar-free version of the original, Coca-Cola Zero aims to taste just like the "real Coke flavour."

Despite their polar opposite advertising campaigns, the contents and nutritional information of the two sugar-free colas is nearly identical.

The Huffington Post investigated which of these two artificially-sweetened Coca-Cola beverages actually tastes better? And if you can even tell the difference between them?

The facts:

Diet Coke

Motto: Always Great Taste

Nutritional Information: Many say that a can of Diet Coke actually contains somewhere between 1-4 calories, but if a serving size contains fewer than 5 calories a company is not obligated to note it in its nutritional information. Diet Coke's nutritional information reads 0 Calories, 0g Fat, 70mg Sodium, 0g Total Carbs, 0g Protein.

Ingredients: Carbonated water, caramel color, aspartame, phosphoric acid, potassium benzonate, natural flavours, citric acid, caffeine.

Artificial sweetener: Aspartame

Coca-Cola Zero

Motto: Real Coca-Cola Taste AND Zero Calories

Nutritional Information: While the label clearly advertises this beverage as a zero calorie cola, we are not entirely certain that its minimal calorie content is simply not required to be noted in the nutritional information. Coca-Cola Zero's nutritional information reads 0 Calories, 0g Fat, 70mg Sodium, 0g Total Carbs, 0g Protein.

Artificial sweetener: Aspartame and acesulfame potassium

Ingredients: Carbonated water, caramel color, phosphoric acid, aspartame, potassium benzonate, natural flavours, potassium citrate, acesulfame potassium, caffeine.

The verdict:

Twenty-four editors blind-tasted the two cokes, side by side, and...

• 54 percent of tasters were able to distinguish Diet Coke from Coca-Cola Zero
• 50 percent of tasters preferred Diet Coke to Coca-Cola Zero, and vice versa

Diet Coke: "Tastes fake right away." "Much fresher brighter, crisper." "Has the wonderful flavours of Diet Coke's artificial sweeteners."

Coca-Cola Zero: "Has more of a sharply sweet aftertaste I associate with diet sodas." "Tastes more like regular coke, less like fake sweetener." "Has an odd taste." "Tastes more like regular." "Very sweet."

Overall comments: "That was a lot more difficult than I though it would be." "Both equally palatable." A few people said Diet Coke tasted much better ... unbeknownst to them, they were actually referring to Coca-Cola Zero.

IN SUMMARY: It is a real toss up. There is not one artificially-sweetened Coca-Cola beverage that outshines the other. So how do people choose between one or the other? It is either a matter of personal taste, or maybe the marketing campaigns will influence their choice.
