It is a very good edition of the game. I've played with the Eon and Mayfair editions also. The FFG one is the best presented, not just in terms of artwork, but in how much the design of the cards and components make learning and playing the game easier.
Furthermore, Kevin Wilson, who developed this edition of the game, really really gets it, and it shows.
One thing, though; boardgame design has changed a lot in last thirty years. Back in the day, CE's utter chaos and randomness was considered a feature, not a bug. These days, many boardgame fans have the reverse opinion. If you prefer games with minimal randomness (say, Agricola), then CE might be too crazy for you.
I think it's one of the best games ever, and its influence on modern game designs of all kinds is pretty evident. "Exception-based" rules design blossomed from CE, by all accounts.
