Both the Caran d'Ache luminance and Derwent Lightfast pencils compliment one an other beautifully, they each hold qualities that the other does not, making them the perfect couple. If I was asked by an artist that they could only get one set, which would I recommend, I think that choice would be as tough as asking me who I love more, my son or my daughter; well maybe not quite that tough, but you get what I mean.
