What are the different types of paprika and how do they differ in flavor and heat level?

There are three main types of paprika: sweet, smoked, and hot. Sweet paprika has a mild, slightly sweet flavor with no heat. Smoked paprika has a smoky flavor due to being smoked over wood fires, and it has a mild to moderate heat level. Hot paprika is the spiciest variety, with a strong heat level that can vary from moderate to very hot.
