Bronzer adds shade to your face. If you are not fond of contour as it seems to be a bit too much and too dark, and not for everyday, a trusty bronzer may be your best bet. When you put on some bronzer on your face, you just add some warmth to the parts of your face that are usually hit by the sun giving you a sun kissed look rather than when you contour which is when you sculpt your face to add dimension. Bronzing also looks a lot more natural.
On the other hand, when you highlight your face, you may start with a lighter shade of concealer under your eyes, on your forehead between your brows, the line of your nose, your chin, and so on. Then afterwards, when your make up is all done, you may add highlighter which is a glittery product. You do this to add more glow to your skin. You add it to areas of your face that you want to stand out that are usually atop anyway such as your browbone, your cheekbones, and the tip of your nose.
Adding bronzer and highlighter to your make up routine does wonders because they give your make up look a more three dimensional feel.
