Brave New World is better, scarier, and much more plausable.
The original dyspotian totalitarian state fiction, We, is well worth reading as well.
Brave New World is absolutely one of my favorite books. Cat's Cradle is very good, too, but I think 1984 is better as a dystopia. The conversation between John and Mustapha Mond is, I think, one of the best I've ever read.
