Obviously the 14 bindings have more metal therefore more durable and the weight can add stability. Is there any other performance reason for a lighter skier who doesn't need the heavier spring to get the heavier binding? In Ski Mag, they made comments for Tyrolia and Volkl (Marker) that the heavier bindings "transmit more energy" and are "more powerful".
If the only difference is the DIN adjustment range and your DIN falls in the range the advantage of the binding with the higher DIN wil be the durability of the spring. This is beacuse the spring will not need to be compressed as much to be adjusted to your DIN. As a result there will be less stress in the metal of the spring. Over time (maybe as little as one year for higher DINs, possibly as long as 10 years for lower DINs) that higher stress in the spring will cause the binding to fail to release at the proper torque per the visual indicator DIN setting. I recommend the binding with the highest range that includes your DIN if all other things are equal.
Look very closely at the bindings you are considering. Some bindings that have a maximum DIN setting of 14 have an identical construction (features, materials, etc) to the binding with a maximum setting of 12 from the same manufacturer. Others do not. I some cases the binding with the higher maximum DIN may have fewer "features" but it usually is made of a stronger (and heavier) material and may have an additional feature or two - some highly desirable.
For a lighter skier I would recommend a lighter binding over a heavier binding if all other things are equal.
