I like a good African or Indonesian coffee...Latin American coffees tend to be too acidic for me. I prefer Caribou. I can't believe a real coffee drinker could prefer Dunkin Donuts or Tim Hortons. They taste like "coffee flavored" water to me. I would ask you to do a blind 'smell and taste' test for several coffees. Open a brand new bag of coffee (whole beans preferred)...smell them...gring them and brew them...smell them. Then taste them. If anyone tells me they chose the aroma of DD or TH over Starbucks, Caribou then there is something seriously wrong. I've done blind studies with customers (I'm in the coffee business) and there is a huge difference in smell. The DD and TH whole bean coffee and brewed coffee do not smell nearly as good as their competitors, like Starbucks. Much of the taste of coffee can be determined by its smell. If you prefer those coffees, then you just have been conditioned to like worse tasting...weaker coffees.
