Trionfi Della Luna and Invisible Light.
I suppose the Serghi Udovichenko Ex-Libris Tarot is the most beautiful contemporary tarot deck. (I think it's also one of the most complex and sophisticated programs of tarot imagery ever done. In my opinion, that adds a lot to the "beauty" of it.)
Though hard to compare different approaches, I suppose the Iona is a close second.
Of full 78 card decks, I suppose I'd look to Corte dei Tarocchi. The original Anna Maria D'Onofrio Portfolio version is quite a marvelous experience to sink into.
