Nope, the PRT Cloner does exactly what Frost+PRTVolume do, minus the mesh part.
With Frost, you make a field and then an iso-surface mesh, then PRT Volume produces a LevelSet from that mesh (so another field), and seeds particles in the field. If the mesh is changing shape, particles will be revealed in some voxels and disappear in other - they won’t move.
With PRT Cloner, the particles are put on a grid immediately, and have an influence radius (similar to how the Frost Radius affects the influence of particles), and new particles are seeded on the grid to represent the original particles’ properties like Color, Density etc.
But if the source particles are moving (e.g. sand castle collapsing), they will be moving through the grid, and the seeded particles will not follow them, but will be revealed as the influence field moves. So both approaches will produce the same look, which you probably don’t want.
Stoke could advect new particles to move with the original ones, but these new particles would have no knowledge of collision objects like the ground etc, so it might not be a perfect solution either.
