The surface map has the slight advantage that you can choose the frequency of the mesh lines (you can select every other one, every 5th one, etc), you can set the limits of the map, and it does not show blanked areas. On the other hand, wireframe maps are vector images (not bitmap images), so they may be a little crisper.
