Hi All
I have used AI Sharpen more this afternoon than I have done since buying it a short while back and thought I would share my thoughts & observations as follows:-
I was preparing some files for printing and as AIS was new in my approach and workflow this was the opportunity to ‘go for it’.
An aircraft in flight just needed the “Focus” setting as I found “Sharpen” seemed to exaggerate a touch chromatic abberation I had not spotted before!
Of the bird (only one image file today) and animals I worked on ~ the bird benefited from either “Sharpen” or “Focus” but settled on Sharpen to good effect 
The 4 different animals files ~ for whatever reason two looked best with “Stabilise” and one off each “Sharpen” & “Focus”. In none of the cases was the animal moving.
So, of my limited experience so far ~ it pays to check each file type with each of the ‘settings’ and see what suits it best for the level & look of the sharpening. FWIW the processing time for the preview was approx 15seconds per setting but provided you do not shift the preview position once all three types have been preview processed you can click the between each one a few times to be sure that you have selected the one ‘best for the image’. oh, the side by side preview with the moveable view slider is great 
Note:- 3 of the animal files were then enlarged in Gigapixel.
Hope that helps and/or informs others.
PS I was not sure this was the correct place to post this
