Paint chips are not bad yet...but make me worry about what they will look like by the end of the season. Last car accident I had didnt do any mechanical damage...but I still didnt want to drive around with a big ass dent in my car. Guess that makes me superficial.
You are not superficial. However, you are falling into ice and snow... this will scratch and chip your bindings. Just as driving your car repeatedly into snow banks would damage your car.
All bindings are going to incur cosmetic damage... it's unavoidable
Unions hold up better than Rome and not quite as good as Burton (from a cosmetic standpoint) but you will never purchase a binding/board that does not show wear after use. None of these cosmetic issues effect how products perform so you have to accept it.
