Well if you really want to know,
Perhaps you are under the assumption that an Action cannot possibly perform as well as a third party plugin because after all "it could only use the built in filters provided by Photoshop".
The trick with digital filtering is that Photoshop actually has many of the primary operators (including minimum, maximum, highpass, custom filter, median, apply image...) that can be used as the building blocks to produce a truely remarkable digital filter. The difference is a 3rd party plugin is a program written in say C or C++, and an Action is written in the "language" of operations that can be done in Photoshop.
The end result depends purely on the ability of the algorithm to perform, not what language an algorithm is written in. Building a complex algorithm as an Action is not a problem either, my denoise Action has over 180 steps.
As for the FFDD sharpening algorithm it is similar in nature to the other highest quality methods in that it adapts the level of sharping to local area conditions around each pixel. So it stops areas from oversharping while enabling micro-sharpening of lower contrast details. This in combination with FFDD denoise, which removes noise only in the direction aligned with the edges (to keep edges sharp), and FFDD double, which as enlarging, thins and thickens details (to try and restore image quality) and micro sharpens around edges, becomes a powerfull workflow to produce crisp images from low noise developed photographs.
If you want to see what it does take a look at this image (full image on top, non-sharpened 100% crop on bottom),
