For the catskills, you just can't beat the NYNJTC maps. Tyvek so they can take a beating and won't get destroyed when they get wet, trail desriptions on the maps, easy to pack even if you are hiking without a pack or anything. The maps from ADK need to be coated, and carrying a book just isn't always practical. It is nice to have the book to have longer descriptions and more info, so I like to have both but the books hardly ever comewith me on a hike.
