My favorite setting as well, I can edit the best shots from RAW, but can share any shot as a JPEG. And those are usually not too bad anyway, sometimes I just stick with the camera JPEG. Only exception, and rarely enough, continous high speed shooting. Even in JPEG Fine, the buffer never runs full. In RAW it does so after appr. 10-13 shots.
Yea, I also do RAW+JPEG, Some times the JPEG turns out just fine and I won't bother with darktable, other times I use the JPEG as a sort of "what would the camera have done" reference, like, for inspiration for the direction I could develop it.
