I’ve compared the two a while ago, seems to me like slightly different takes around the same core ideas. It’s true that a couple of things in Ansel feel more natural, but it’s not much, and it’s probably not worth the risk (AFAICT the bus factor is one, compat with DT isn’t a goal).

Darktable developers pride themselves for their non-destructive processing pipeline and use it as an excuse for how quirky and inflexible their UX is. I believe they are highly competent on the highly technical bits that ultimately very few people see or understand. Personally I can use it to an extent if I unlearn what other software have taught me over decades of UX conventions.
