I have converted over 3000 raw files using AP and cannot identify the problems described above. It all works according to the design of the app which does have some differences in the way it does things from Photo Shop. For anyone wondering about this "issue" I recommend readiing the PetaPixel review and rating for AP that I quoted in my original post.
The article makes no mention of the quality of AP's raw development. It only acknowledges AP converts raw files.

And so since the article made no mention of the quality of AP's raw Develop module, suggesting the article is different than my assessment is deceptive.

To repeat, they found AP to be the best overall software alternative to Photo Shop, and that's of all other software in existence.
To repeat the article made no comment about the quality of AP's raw Develop module. Like the article I also said AP is the best alternative to Photoshop.

And if that's all you had done I wouldn't have commented.

People may be considering buying AP and people may be looking for photo processing software and see this post. Those people deserve good information if they're looking for facts to help make a decision. Here's some facts:
AP is a direct alternative to Photoshop and of the all the other options it's the best alternative. If you're looking for something like Photoshop but don't want to purchase Photoshop AP is your best choice.
AP is a raster image editor like Photoshop. Raster editors work with RGB image files and are able to directly alter the pixels in the file. Raster editors can not work directly with raw data and so raw files have to be converted first into RGB images for a raster editor. This is the same for Photoshop as it is for AP. To convert a raw file to an RGB image Photoshop is supplied with ACR (Adobe Camera Raw) and AP is supplied with it's Develop Persona.
Although I would agree that AP is the best raster editor alternative to Photoshop, AP's Develop Persona is a poor alternative to ACR. (Again a simple solution is to use AP but have raw files developed with other software.)
The biggest difference between AP's Develop Persona and ACR is that AP's Develop Persona will not save your work. ACR of course does save your work as does every other raw converter with the glaring exception of AP's Develop Persona. This means of course that should you reconsider the way you did something in AP's Develop Persona you can't just go back and change that but you have to start from scratch. Let's repeat that
all other raw converters you can use will save your work.In the earlier referenced PetaPixel article the first criteria they mentioned that was important to them was the ability to work non-destructively. I agree! I would rate that criteria way at the top of what I want from photo processing software. Once AP has an RGB image in hand it does a good job of working non-destructively. But if we compare ACR and AP's Develop Persona for raw file conversion we find a big difference. ACR has the ability to pass what Adobe calls a Smart Object over to Photoshop -- it's the RGB image with a link back to the raw data. So that while in Photoshop working on the RGB image you can actually click the Smart Object link and go back to ACR where all the work you did there is of course saved, make a change and that change will update back to Photoshop. This is the gold standard for non-destructive editing with a raster editor -- your raw editing work is included. AP has nothing like that and in fact because it discards your work when the raw data is converted to an RGB image there's nothing to go back to.
AP's Develop Persona has no support for camera input profiles. You're simply stuck with whatever they provide and you don't even have an option to bring your own. Again ACR comes with dozens of input profiles including good simulations of the ones in your camera and also the ability to add your own. Again this is standard for commercial raw converters.
Camera input profiles in LR -- yes.
Camera input profiles in ACR -- yes.
Camera input profiles in C1 -- yes.
Camera input profiles in PL4 -- yes.
Camera input profiles in RT -- yes.
Camera input profiles in ON1 -- yes.
Camera input profiles in SilkyPix -- yes.
And the list goes on.....
Raw files have red, green and blue color channels. Rarely do they all clip together. Most often the green channel clips first before the red and blue channels. When that happens a raw converter can step in and help by performing what we call highlight reconstruction. The software can basically use the data in the two intact channels to fabricate appropriate replacement data for missing channel data. We expect this effort from a good raw converter and it's a criteria that we judge them on. LR/ACR and Capture One lead the pack. They both do a terrific job of highlight reconstruction. But the other raw converters at least turn in a respectable performance. Even the FOSS programs RawTherapee and DarkTable do a good job at highlight reconstruction. Almost all of them at least try, well, except for AP's Develop Persona that doesn't even try.
Before you commit and convert your raw data to an RGB image you want to cross your Ts and dot you Is -- there's things you should have done before that big step. You need tools to do that work. For one make sure you're not clipping a color channel. For example a photo of a red rose can very likely clip the red channel and you want to catch that and fix it before you convert the raw data. The ideal tool for that is what we call an HSL (Hue, Saturation, Lightness) tool. Of course ACR has one. I can't think of any raw conversion software that doesn't.... oops, yes I can. The Develop Persona in AP doesn't have an HSL tool. That's just nuts -- not ready for prime time.
