I've just recently been combining Photolab with Darktable. DeepPRIME really is a killer feature. It produces images that are basically noise-free without turning the whole image into a smooth featureless blob. But I also really like Darktable's Filmic RGB module and colour management (you can output P3 images and actually make use of the wide gamut displays that nearly every modern device has). So I've taken to this process: - Cull my images and putting everything but the ones that make the cut into a "Rejected" folder. I used FastRawViewer at first but I've warmed to Digikam. - Run DeepPRIME and DxO's optical corrections with Photolab and export a DNG. - Do final adjustments and exports in Darktable. Basically, Photolab allows me to use Darktable but skip Lensfun (which others have mentioned is a bit of a weak point in Darktable) and push my shadows as far as I want without noise.
