Quick answer
Both are Level 3-4 with comparable processing. Both add sugar (or high fructose corn syrup in some Ragu varieties), soybean oil, and citric acid. Neither approaches the simplicity of a homemade tomato sauce or premium brands that use olive oil and no added sugar.

Frequently asked questions
Is there a processing difference between Prego and Ragu?
Very little. Both use tomato puree with added sugar, soybean oil, salt, citric acid, and dried herbs. Some Ragu varieties have used HFCS, while Prego generally uses sugar. Both are Level 3-4 commercial pasta sauces.
What is a less processed pasta sauce?
Look for brands with short ingredient lists: tomatoes, olive oil, garlic, onions, basil, and salt. Rao's Homemade is a well-known example at Level 2. Homemade sauce from canned San Marzano tomatoes is Level 1-2.
