I find that with polymodeling I like to bevel the edges instead of faceting the points. In real life there are very few “straight” edges and even the slightest bevel on an edge gives a nice definition that empasizes the 3D nature of the object. Usually you need a poly bevel with at least one division to make this work effectively. Bevels also work well if you are using subdivision surface rendering.

When I model these days, I share points as I go. I then build sharpish edges by bevelling them, sometimes with PolyBevel, sometimes PolyExtrude, sometimes just cutting in with PolySplits.
Take a look at Mario's boxes in his hip files for the glass wip on Od force:

All nicely bevelled edges and render nice, crisp and well behaved.
Aren't those razor sharp unshared edges too CG these days?
Ultimately you need to build the edges proper with poly detail so that you can render with subd's and with GI.

There's at least one school like the old school!

The PolyBevel SOP is my best friend. But it should be noted that sometimes if you receive a 5,000,000 polygon object to work with going through and beveling everything can be a year long project. In cases like this the Facet SOP with Cusp Polygons can help save the day.

It's often important to add an extra span outside of the polybevel result or you'll end up with normals being interpolated across what you'd expect to be a flat surface. I usually use a polybevel set to “corner” followed by another polybevel set to one of the round options in order to get around this.
