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 :)
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.
