Do you really prefer your Bon Cajun to the Acadian? That really surprises me. I'm really partial to the keyboard and sound of my Acadian C box, though I understand that every box -- regardless of the builder -- has its own feel.
I don't want to gush too much over my own "brand", but I've always thought of Marc as a true innovator in the art of accordion-building. His boxes have a playability that I find unmatched elsewhere.
Granted, "feel" is very subjective, but I think that the reputation of Acadians as being the "standard" is very well deserved.
The quality of Quebecois boxes is also extremely high, particularly in terms of craftsmanship, but their keyboards have a very different feel (more of an Irish style).
