Software differences between Photo AI and Sharpen AI?

What are the actual software differences in terms of final result between PhotoAI and SharpenAI?

I recently achieved a far better result in SAI than in PAI despite the fact that the former hasn’t been upgraded in months. If you look on the TPAI general thread you will see the results I posted.

HI. In this result I don’t understand exactly what I’m looking at. A test could be to work the exact same file with the same settings with both software.

If you look at my post on that thread with the example, you will see what conclusion I cam to in that instance.
