I like the second version, but only if I don't think of it as an improvement or a replacement - but as a different deck in its own right. The changes are profound enough for the deck to be considered another deck.
The original is one of my favourite oracle decks. I have always loved space exploration and photography, and I was so enchanted to find out that an oracle had been made out of the Hubble photos. So I shall definitely be keeping that one and continuing my work with it.
But as I said, the other one has its charm. It is more readable without the help of the book, I can imagine.
I would call it something else, though. Because to me, the Universe Cards will always be the original cards.
