Also at the time of buying it I decided to go with the HDF version, and quite frankly I never use the HDF filter, because the effect is too strong. The only occasion where I would consider it is if it's a directly lit object without the light source in the frame, so as to produce a soft glow. And it's also ok on overcast days as in this pic.
Other times I tend to use the "Soften" module on darktable to do a much better job (mostly because it's controlled, even if I have to use masks on some lamps sometimes).
