I used Ansel for a while, and I agree that Darktable is suffering from feature creep. Ansel right away had some usability improvements. But the amount of regressions introduced was wild. The anger you can read in the messaging was apparently also employed to cut code, and things got flaky. In the end some features I used stopped working in all releases I tried, and I went back to Darktable. Maybe Ansel is stabilizing now, and I should try again.
