Dry food is flavored with a coating of animal digest to make it palatable to cats (it acts as a flavor and scent enhancer). It's entirely reasonable to assume that different sources of animal digests from different manufacturers will have different flavors, and that your cat prefers the particular flavor from a certain manufacturer.
In addition, Dr. Karen Becker explains
there are research and development departments in many of the big
commercial cat food companies whose job it is to study what shapes
cats prefer. Whether it’s an “x” shape, a triangle, a circle, or maybe
a tiny fish, the goal is to develop products your kitty will demand
once he’s hooked.
So if a particular brand all share the same shape, then your cat is expressing their preference for that particular shape of food.
John is right that cats don't easily change between food, but I do generally recommend a rotation of at least 3 different brands/flavors so that your cat is not in any danger of Feline Hepatic Lipidosis if the manufacturer suddenly changes their formulation to something your cat finds unpalatable.
In addition, a food rotation also can protect against accidental nutritional deficiencies due to manufacturing error. An article found on Pawnation reviewed a study that found:
"Since 2009 [article published September 2013], there have been 5 major voluntary pet food recalls
involving thiamine-deficient pet foods in the United States that
ultimately involved 9 brands of cat foods and at least 23 clinically
affected cats. Most of these recalls were instituted in response to a
report from a consumer or veterinarian after treating a cat that had
clinical signs consistent with thiamine deficiency."
