I learned on the Celtic Dragon Tarot, which were these huge massive cards. Actually I used Hanson Roberts for a long time which was a mini deck. I finally got a Rider Waite many years later and it is now my main deck. Am even considering buying a second at a different size factor. If it's necessary for you at some point to get that deck, you will find your way to it on your own, I think. I resonate well with the RWS. The Hanson Roberts didn't feel as transparent for me but I used it for many years reading myself and others without any problems as it was my primary deck.
