There is no definitive answer to this question since the strength of coffee can vary greatly depending on a number of factors, such as the type of bean used, the grind size, the brewing method, etc. That said, many coffee drinkers believe that K-cups tend to produce a stronger cup of coffee than regular drip coffee. This could be due to the fact that K-cups often use a finer grind than regular coffee, which results in more contact between the coffee and water and thus a more concentrated brew.
