I can see wet sponging being able to smooth out bumps and lumps in bad drywall mud jobs but I fail to see how it would flatten the mud so that it has a slight taper to the paper surface and create a level surface that will not show through the paint finish. Basically, I don't see a wet sponge having the control of a large flat sanding pad when finishing a drywall seam or screw dimples. This is my personal opinion, others may differ.
