I used Sharpen AI on this file and was shocked at the sharpness improvement. This is the Stabilize mode. Image is a screen shot at 100% from the Lightroom Comparison screen. Lens was 40-150 2.8 with MC14 at 63mm, a lens that is no slouch in the sharpness department. F6.3 at 1/320 with stabilization so camera movement should have little effect on sharpness. From the car with arms supported so that should further help the sharpness.

I don't know if the web presentation will kill the comparison, but sitting at my screen in LR the difference popped out at me.

The new four view feature really helps in getting the best result. You have four views in a quadrant: original, sharpened, stabilize, and focus. Select and area for examination then update each of the three modes. You can select the one that you think gives the best results. I thought I knew which mode would be best but I have been surprised when another one is better. So my advice is to check all modes. In some tricky situations I check different areas of the image for comparison.

One gotcha is that the preview seems to show the image with enhanced grain, more than the original. This is misleading because when the file is processed and back in LR, the grain is actually less than the original. My advice is to process disregarding the grain in the preview and to check it in LR. In most cases the grain will be less but in some few cases it may be increased slightly.

There is always the chance of artifacts from too aggressive sharpening. I almost always use the Auto option and have not run into this. The focus mode seems to generate the most artifacts especially when it is the wrong mode for the image. In a couple of cases where I thought artifacts would be a problem, in the processed version at 100%, the artifacts were minimal and did not show at normal magnifications. In any case the resulting processed image was better than the original.

The sharpness difference is noticeable on the web comparison but no where as dramatic as on my LR screen.

I agree that Topaz Sharpen AI is very good. You do have to pay attention to the controls, however. There are 2 Auto options , one to pick the type of sharpening (Sharpen, Focus, and Stabilize), and more importantly, IMHO, an Auto option to pick the amount of sharpening based on analysis of the image. This is what you are referring to, I think.
When I first started using SharpenAI, I noticed that it always seemed to start at 50/50 for sharpening and noise reduction. I erroneously figured that it had analyzed my image and come up with that (which seemed odd after about the 3rd time). No, you should pick the Auto Analysis to get it to suggest amount of sharpening and noise reduction. It usually reduces both significantly, but at least in my installation I have to click this each time I use it (maybe it will remember; not sure).
The other Auto toggle is for the type of sharpening. There again, if you click it to make it automatic, it might pick a different mode than the default (Stabilize, if I remember correctly). This is less important, I think, because I often override it even after it has picked a mode, because you often can tell if an image is OOF or has camera shake. Anyway, pay attention to those Auto buttons to goose it into giving you a suggestion! :)

Today, the main website is showing $79.95? (ie regular price) Are you referring to a discount code?
I am not sure since I was just passing this along from Anthony, I know he also has a discount code if you purchase thru his site.Plus the review is good.He mentions the sale at 6:45

I don't think Sharpen is currently on sale per se, but you can utilize the discount code. When on periodic sale, you typically can leverage both discounts.
