Keep in mind the default sharpening setting for ACR is +25 for all RAW files types (with no regard to the camera, lens, etc). This default value is evident in the EXIF of the first image of this post.
For my own work, I prefer a higher value as well as refinements to the Radius, Detail and Masking values where the same sliders exists in LR as in ARC. Using the <ALT> key against the slider gives a better understanding of the purpose and impact of each of these sliders.
Although this post appears to be specific to CS4, it actually applies to two other Adobe products (LR, ARC) for explaining the sharpening sliders: https://www.photo.net/learn/camera-raw-sharpening. I've found a masking value in the 55 to 95 range (depending on image content) has the most impact (refinement) on the quality of the results.

I believe the default sharpening in the current Lightroom is now +40.
