The one and only difference between personality and gimmick is that a gimmick either is or feels cheap. You only know that something is a gimmick because it doesn't work on you. If it did, you would call it "personality". When you discover a gimmick in a product, you usually feel "cheated" because you realize that this product was not designed with you in mind but was designed for an audience whose abilities to tell a gimmick are less than yours. This leads to realization that acquiring said product will not add any marketing edge to your persona (you won't be able to impress people who matter to you with the product).
