From my little collection, the
Daniloff tarot stands out for its artistic quality. It's a wonderful and very personal interpretation of tarot archetypes, medieval illuminations (especially Carolingian) and expressionist art. It's a fascinating deck.
The Wild Unknown has very good art, too, and I love it because it also reads well. The ink drawings with miminal colour touches give unusual, enigmatic, unsentimental images of animals.
Margarethe Petersen is an interesting artist but I have problems reading with her deck, much as I appreciate her art. It's both figurative and abstract, a very interesting use of colour and texture, and it's better for meditation than readings, at least for me.
The
Light and Shadow has really good art, too. I have a weak spot for lino and wood prints, and the stark black and white, the clever use of positive and negative, and the expressive use of line and plane is masterful IMO.
From an artistic point of view, these are among my favorites.
Honorable mentions for Dreaming Way and Shadowscapes! Their art is more illustrative-narrative but very very good, and less abstract than Petersen or Goepferd's art. That makes for better reading.
I find that for their function as tarot cards, artistically less successful decks can work better. Puzzling but that's my experience. It seems that aesthetic quality is not everything, not even first priority in a deck.
ETA: I didn't know the New Century deck before but I agree, it has excellent art.
