Rao's is the best jarred pasta sauce on the market. Mario Batali's isn't better, but considering that it is cheaper, how close does it get to Rao's? Pretty close, but given the choice, I'd still take Rao's. I compared their vodka, marinara, and tomato basil sauces, and without fail, Rao's sauces had more punch to them, were heartier sauces with greater chunks of fresh ingredients, and also had more body, whereby they coated my mouth with flavor.
Batali's sauces, in contrast, were universally thinner. They were much lighter sauces with milder flavors, body, and few chunks of ingredients. The sauces tasted far from bad. For example, the tomato basil was rich, smooth, and had a fresh, sweet flavor to it. Everything about the sauces was smooth, sweet, natural, with just the right amount of salt to bring flavors out. They're just so lacking in body and flavor in comparison to Rao's sauces, though. Rao's uses more seasoning, more garlic, larger amounts of fresh ingredients; truly, everything about Rao's is one (sometimes small) step above Batali.
Still, if you can get Mario Batali sauces, they're good in every way. A high-quality sauce for a fair price. Jars usually run in the $5-7 range, but I think that I would always opt to spend the extra $2 on Rao's, given the choice.
