I prefer Coca-Cola. Their colas taste better than Pepsi's and is especially good when it's been in the fridge for 2 hours.
And as for Mountain Dew, it used to allow me to give Pepsi a point, but that was before Coca-Cola released their Vault energy drink, so now I like Vault better than Mountain Dew. Plus, I like the extra energy.😀
Dr. Pepper is good, also.
