Bonding VS Componeers? (photo)

All of my teeth have fillings, including my front teeth. Even though I can afford porcelain veneers I chose dental bonding to fix my front teeth because I feel it looks a bit less fake. However, my dentist just got a set of Componeers from Coltène/Whaledent and he wants me to have instead the Componeers. Would bonding or componeer veneers be the right option if a). I desire my teeth to look as natural as possible and b). I want to avoid further tooth reduction.
