Ragu Pizza sauce vs. Ragu Pizza Quick sauce

Ragu makes two pizza sauces. Ragu Pizza Quick sauce (for $1.50 a jar) and Ragu Pizza sauce (for $1.00 a jar). I always get the cheaper one and it works fine in my pizzas.

Given that, does anyone know what the difference is, other than price?

I asked ‘Mama’ at Ragu’s website and got the following

So, the quick sauce is better for breads and english muffins because it’s thicker.
