It's ok, but to be honest I prefer the original. It's mostly the new card decks for me - the simplicity of just one deck, with everything on the card, was a better fit to my mind than the three separate decks in Eternity. The special stuff (spells, psychic powers, miracles etc) are all now a little too samey for me too - something that put me off Savage Worlds compared to original Deadlands. I'm all for simplifying mechanics, which Eternity does, but you could still have different spells / miracles / psychic powers using the same simplified mechanics, rather than making them all have the same powers. It's still pretty crunchy too, not much less than the original. I'm not that keen on the new experience rules either.
It does do some things better than original (and the simplifications do go some way in the right direction, if not enough for my liking), but overall the feel of Eternity is a step down for me rather than a step forward.
