Question RE: Stephenson and Gibson (Score 2, Interesting)

I read Cryptonomicon a year or so ago and loved it, and also really liked Snow Crash. So I went to check out one of William Gibson's books and found that Idoru was the only one at my local library. I checked it out, but after a couple of chapters I gave up. It just didn't impress me.

My question is, is Idoru considered to be among Gibson's best work? If not, what's the best introduction to his style?
