I do agree it's good, though I personally prefer Diamond Age, but I also think it has the Standard Stephenson Ending Problem. The ending really is a great action sequence, and resolves the immediate problem that the action sequence was about -- Snow Crash is disarmed -- but it's also more a stopping-point than an actual ending to the plot. There's a lot of "what happened next?" both with the overarching stuff and with the specifics of what happened to all the major characters, so there's not much closure.

There's a certain amount of circumstantial evidence that Diamond Age is set in the same universe decades later, which probably answers at least a bit of that, particularly if you assume a certain character is Y.T. based on one reference. But still, that's not much of a save for Snow Crash viewed as a complete story in itself.
