PL is a full post processing program. DXO is primarily a denoising program that is to be used in conjunction with your chosen PE. DXO PureRaw5 looks like it will add some more options--but not a full blown PE. From AI response '.....From what I just saw when I tested both, PureRAW is very basic: just lens correction and denoising. Though it can export to DNG, which isn't common. It's really meant to be used for batch processing all your photos (by default, it doesn't even show the traditional panel with the processing tools, I had to search for it).
In comparison, PhotoLab has more processing tools to crop, rotate, change the perspective, adjust the colours, retouch the photos, etc. It even allows to mask the part of the image to process. But it's not a fully-fledged image processing tool like Affinity Photo or, I guess, Photoshop (e.g. you can't draw, use layers, etc).
Key points about DxO's leadership:
- Lens correction:
DxO is widely recognized for its extensive database of camera and lens profiles, allowing for precise correction of lens distortions, vignetting, and chromatic aberration.
- Noise reduction:
Their "DeepPRIME" technology is considered one of the best in the industry for effectively reducing noise in images, especially at high ISO settings.
