OK, I'm in both camps, so to speak. I definitely want companion books, but like so many others here I find the boxed sets are a pain in the rear to store. And most boxed sets don't have an inner tuck box or chest box for the deck, so splitting the set up is problematic if you like to keep cards in their original boxes. And now of course some decks that originally came by themselves now come in sets, and try to find the companion book by itself! But if I could do it, I'd have all my decks by themselves in the box or bag with all the others, with companion books that would sit on a bookshelf with all those others.
