Gauge potentials are more fundamental in the sense that they are the ones that arise naturally as connection 1-forms on a [math]G[/math]-principal bundle in gauge theories, not the physical fields themselves. However, the kind of equations they satisfy depends on which gauge you chose for them. The Coulumb gauge leads to the scalar potential satisfying the Poisson equation in electrostatics, for instance.
