My trial version of Bibble was awful, IMO. After 20 minutes I knew it wouldn’t work for me. There were terrible banding and posterizing near bright areas such as the sun and the tonal gradations near the sun.
The two best are Capture One and Raw Developer.
Capture One handles tonal gradations and the sun very close to film. I don’t like the interface with Mac, however.
Raw Developer may be the best raw development software available, good price too at $99. It is ONLY available for MAC (sorry PC users), its extremely fast, and gives you more control over the image than anything else.
