Aesthetically, and "business" aside, the Cariter dial speaks to me more because of its greater symmetry. One might argue that if you're going to execute a very visually active design, à la the Sonata, then a degree of symmetry might help to ground it. Conversely, if you're going for asymmetrical, than keeping it simpler may strengthen the design - think of the Lange 1 or the Breguet Classique 3137.
