I think it's all relative. When I first started processing RAW I downloaded Darktable and have been pretty happy with it since then. It's an excellent, powerful open-sourced program. Based on information from @Darmok N Jalad I purchased Affinity because it can also do editing, unlike Darktable which is mostly processing. I messed with it some, but it's set mostly unused until just this week when I decided to make an effort. Part of my testing has been to process the same image in both programs to make sure I'm getting the most out of Affinity. I have been very happy with it for the most part, but it's also apparent that some images come out better in DT than in Affinity and visa-versa. That doesn't mean I'm dissatisfied with either, both do an excellent job and are very cost effective. I'd be willing to make a guess that if you were to compare LightRoom with your current program in a similar manner you'd find the same thing. Some come out better in one, some in the other. Just a thought.
