They're probably two of the best pagan decks with regards to adherence to tarot symbolism, a good selection for comparison. However, one drawback for some pagans that they both have is a focus on wicca. If I wasn't particular about tarot decks having tarot symbolism, I'd prefer Gainsford's Northern Shadows to either of them. But I favor the Old Path as a tarot deck, followed by the Druidcraft, mainly since I prefer the Old Path Majors (though my favorite pagan deck is the World Spirit).
The OP High Priestess, Empress and Emperor are excellent as well as the Lovers and Chariot. The Wheel of Fortune is another great OP card with the depiction of seasonal change. I like how the OP Hanged Man retains the sense of playfulness, and costume, of the Fool, recalling the dance of the Marseille Hanged Man. Though my favorite overtly pagan tarot devil is the Wheel of Change tanist (from a conceptual, not artistic, viewpoint), the serpent in the OP is a good interpretation. The OP astrology cards, star/moon/sun, are fairly weak. Also, I don't like the tower-as-literally-somebody's-head Tower interpretation, at all. I like the renaissance minors and even a few of the court cards though there are a few that bother me, especially the cheap-bowl-cut Knight of Pentacles. He was probably based on someone she knows since she likes using people as models for her tarot drawings.
The Druidcraft has some really nice cards like the Fool, the Empress, the Hermit and the Moon, but it also has several not-so-nice-for-my-purposes cards such as the etching-a-magic-circle Wheel of Fortune, , the disco-chicken Magician, the Texas-Longhorns/Beavis&Butthead-hand-sign Hierophant, and the sleepy-time Lovers and Devil. The minors are sufficient and the court cards are probably the best of any pagan deck. If you like the Druidcraft, I'd probably just stick with using it since it is a really nice pagan deck.
