I'm curious as to which ones they do not have compared to Adobe products.
The only one I can think of is proper material layer painting in Blender, you can get there with addons but haven't found one that's as good. Genuinely the only thing that I miss, and I do this full time.
Darktable has some features that RawTherapee doesn't, and vice versa. I imagine that some of that stuff isn't in the Adobe software. (I've heard that recent versions of Lightroom have removed local file management support, which both these programs still have – though don't quote me on that.)
