Stephensen's best book, by far----
The others seemed to stay in the shallow end of the pool, but were somewhat entertaining.
Snowcrash is in a class by itself (although not up to the standards of Gibson's Neuromancer)

Where's the love for Bruce Sterling? Go read Distraction - a political thriller set in dystopian, post collapse Louisiana. Its as tight as Brazil in terms of predictive power, at least from my perspective.
