If you search for the best address books, you must try FIS, Moleskin, and SMYTHSON. However, the selection depends upon your requirements. If you are looking for a book that can fit your purse, go for pocket-sized address books. In contrast, if you have a massive list of contacts and many details to put in, then go for a large-sized book with much space for the details. Also, look for a high number of pages in this case.
