Agree. Miracle Whip has its place, but it is not mayonnaise and should not be part of this test. Much like Cool Whip vs. whipped cream.
I also think it’s silly to universally state that “nothing compares to the homemade stuff,” because there are plenty of homemade mayo recipes that don’t taste good at all (also, both execution and the quality/flavor of the ingredients are dependent on the cook). Also, homemade mayonnaise does not perform like commercial mayonnaise in certain applications where stability is important (deviled eggs, tuna salad and the like). I certainly enjoy a well-executed homemade mayonnaise made with a tasty fat and acid as a dipping sauce for fries or a sandwich spread, but for use in recipes, commercial more than “compares,” it outperforms. Especially the heavy duty stuff (Hellman’s Extra Heavy is my favorite).
