There are slews of items that have laws governing them. Milk is milk. Butter has to follow a formula. Flour is flour, rice is rice.
Butter might feed their cows differently, though, and flours have different gluten contents. Rice can be different varieties. In all of these, however, there isn't much different.
Other things are preferences. For example, my father preferred any-brand-but-Kellogg's corn flakes, but my spouse is in the only-Kellogg's-will-do camp. There isn't much difference between brands after that: Kelloggs flakes tend to be thicker and it changes the taste.
There are slews of store brands that are much better in taste - and ingredients - than their name-brand counterparts. The store brands aren't spending lots of money advertising, after all, and can invest that money into making products that are yummy. Having good-quality store-brand products gets people into your stores.
