My absolute favorite is Stand on Zanzibar by John Brunner, The Jagged Orbit was also excellent. Other than that, of course Snow Crash is a masterpiece, but I think my favorite Stephenson book is The Diamond Age. Another excellent one is Daemon by Daniel Suarez whose books are quite fascinating and look at generally pretty topical plotlines (I was just thinking I have to revisit his book Kill Decision about AI enabled killer drones).
