 | Dr Pepper and Mug Rootbeer are similar, but are also very different. For instance, they both have a slight spicy flavor. Mug Rootbeer is creamier and slightly sweeter. It also tastes just like all other rootbeer brands. However, rootbeer may have medicinal properties due to the mix of herbs that it contains. Dr Pepper is an original, and no other soda tastes quite like it, although many come close. It is also more versatile, because it can be drunk hot or cold or even with chocolate milk. Overall, Dr Pepper is my favorite because its unique flavor just tastes better! |  |
