I would not expect a "better" unit buying the Sprinter-based Class A (Via/Reyo) vs the Sprinter-based Class C (View/Navion). Winnebago uses the same materials, house components, production methods and workers to build both lines, and they are trimmed to a similar level. The biggest difference is that the C comes with a Daimler-made cab built to automotive safety standards for the vehicle, the A you will be driving from inside the house structure in a Winnebago cab.
Your choice should probably be made based on how well the living space fits your needs. In my RV club experience the past eleven years, most of the second thoughts, buyer remorse and trading for "something better" has to do with the living arrangements not fitting the buyers' needs.
For children of appropriate age, I like the over-cab sleeping space of a C, because it gives them a space they can consider their own. You can get that in a bunkhouse RV as well, but not at a size this small.
