What they said
The amount of "talkitiveness" of a deck depends on how the imagery "speaks" to you. And that imagery will speak to one person differently from another. For instance, there are a lot of people that hard-core love the RWS. I can't stand it. It's flat and dull and boring and blech to me. I can read with it, but they are mechanically, keyword based readings, because the deck does very little for my intuition. My Shadowscapes on the other-hand? Yeah, that one just goes on and on and on for me!
The very first deck that really, really clicked for me was The Tarot of the Old Path. I've gone through three or four copies of it by now. Until then, it was all by-the-book, keywords and numerology to get the meanings. Yes, I gave accurate readings with decks before then, but that one? That one REALLY spoke to me. I've since found many other decks that speak to me. And which deck is speaking to me at any given time will depend on my mood and what I happen to be going through. When I was going through my separation and divorce, the dark decks really spoke to me. Now, it's all faeries and fantasy
