Okay, so this has to do with how much coffee you are making. I am the only one that drinks coffee. Also, I only drink one maybe two cups a day. I'm not one to drink a whole pot by myself. Therefore, I love my Keurig, it is fast and easy. I can just get it on the go and not worry about anything.
However, if you drink a lot of coffee at one time, or more than one person in your house drinks coffee with your. The coffee pot is your better option.
For me, it is what is best for my lifestyle. I need something fast without making a whole pot that will get wasted.
