I’m growing more and more impressed with its capabilities the more I use it! Wrapping my head around its approach to masking, and its “scene referred pipeline” took some time, but now that I’m getting the hang of it, I think I can say I genuinely prefer it to Lightroom.
Combined with digiKam, which is excellent for photo collection management, I’m a very happy photographer :)
I’m seriously doubting the image quality bit
In terms of noise reduction which greatly affects image quality it is nowhere near the big commercial players.
Have you tried the “Denoise (profiled)” feature? It applies auto de-noising per your camera model and metadata quite nicely. You can then fine tune it after enabling the feature.
I usually leave it at chroma only as well. Luminance noise is far less unpleasant on the eyes.
