Image quality in different photo organisers

Do you mean the quality of the image when browsing and looking at a photo grid? That depends on how each organizer is configured to display previews, so it is possible for organizer A to have better or worse image quality than organizer B depending on how you set up previews on each of them.

Or, do you mean the potential image quality of an individual image when you edit it? That depends on an organizer‘s image editing processing engine and feature set in the organizer, and generally, yes, they can produce different results. For example, if two organizers each have their own image editing module, they might have different capabilities of editing tone and color precisely, or different support for profiles/presets/LUTs.

What is your goal, what kind of image quality is most important to you? Quality for producing web images, print images, HDR images, wide gamut images…? Something else?

From the organizer? Very unlikely.

Please be specific, what organizer(s) are you talking about? Are you talking about RAW original images or JPG original images, or something else?
