Sriracha and sweet chili sauce are two different things. Where sriracha packs an element of heat, sweet chili sauce is dominated with a sweet garlic taste. Apart from being a lot less chili, the flavor profile is almost the same, but keep in mind that sriracha sauce is different from tabasco or any other hot sauce. It is much thicker with a strong hint of garlic and sugar, particularly the Huy Fong variety that is most popular.

Despite its misleading name, sweet paprika, of which Hungarian paprika is one variety, isn't sugary or sweet at all. Instead, it's called sweet paprika to distinguish it from other types of paprika that are spicy. The end zing, or lack thereof, depends on what type of peppers were used to make the spice. Some paprika is made from red bell peppers, while other paprika is made from chili peppers. If you don't have sweet paprika on hand, you can use any number of substitutes, many of which will yield flavorful results.
