To a large extent it depends on what you plan on doing with your prints. If you hope to market them with multiple copies nearly identical, then it would be important to ensure a good negative that's repeatable. If, however, you view them as fine art prints with each print having some individuality, then its important to get a negative that has all the information you need to work with. Then your darkroom skills and post-visualization will come into play. Personally, I like the challenge of a high contrast negative, for example. There are so many ways to interpret it.
