I would go ahead and get the field guide. It, like the first edition, was independently compiled, which I think adds some value in identifying errata that always can occur with such a magnum opus (although they did a good job of vetting a lot of the original errors from the first edition).
The real value of the field guide, for me, is getting some specific information on objects that the atlas can't convey. The notes on the objects, of course, are valuable intrinsically. But information like major and minimum axis dimensions for galaxies and surface brightness data (against the visual magnitudes) can be enormous in judging what you might expect to see in a given telescope.
You may not use it every time you use your primary volumes of the atlases, but when you need it, you will likely be glad you have it available.
