It's more controllable. Sharpen does a generic sharpen which may or may not be right for any one image (it's right like a clock - twice every day - by default).
I use USM on almost every picture I post process. I would never use "sharpen" or "sharpen more" again. They are beginners tools that once you understand USM you would never use again.
Also, I high pass sharpen when USM doesn't work.

If you search the forums, there are several threads with details of how people use this. There's also a DPC Tutorial here, under the "Learn" menu.
You can see some examples of the varying settings in this gallery at pBase. |

HOLY COW! :) High Pass sharpen is awesome!
Thank you, i never noticed that high pass tutorial there! I always hated USM for the added noise and the lack of undo after save... I tend to oversharpen my images on the first pass, and forget to duplicate the layer, and next day when I realize its oversharpened, I have to re-do all my changes....
Is the High Pass sharpen legal under the basic rules? |

No to the "Basic Editing" part. The first step listed is "Select Duplicate Layer." Only Adjustment layers (which by definition do not contain any pixel data) are permitted under the Basic Editing rules. It also uses the "Hard Light" layer mode, which is also not permitted under Basic Editing (all Adjustment Layers must be applied in Normal mode).
Such a technique is definitely OK in Advanced Editing where full use of layers are permitted.

These are the 3 ways i use USM...
My camera is set fgor minimum sharpengin, so first thing i do in PS is run USM with these settings:
Amount 500%, radius .1, threshhold 1
I then edit, etc.
After resizing to final size (600 to 640 on the long side for entries here) i run it again, with settings approximately 150%-200%, .2-.4 radius and 7 threshold.
If the pic seems to have a haze to it, you can remove it with USM 30-40% range, 60-80 radius range, and t-hold of 1. The only downside to this is that if there are nearly blown out pars of the photo this will puch them over the edge. But it will remove that hazey look and make a picture POP.
For printing, on an inkjet do very little if any sharpening. If getting them printed on a big machine (like the Fuji machines walmart etc use) do NO sharpening, excpet mabe the first step i use above. The pic will get too busy.
USM will increase the final file size a bit.

| Here is an article @ fredmiranda@com which I think works pretty similar to High Pass |

Another technique I have used with good results is to create a dupelicate layer, then apply USM to that layer and change the blend mode to luminosity.
IF the image has lots of color noise, you can the duplicate the sharpened layer and apply Gaussian Blur to that until the unwanted colors are blurred away (I have good results with a radius of ~4, but YMMV). Then change the blend mode of that layer to color. The grainy structure is still there, but the color is gone.

No wonder I have so much trouble with sharpening!
