For me, he has more misses than hits. I hated Seveneves. I hated Fall so much I quit maybe a quarter way through. I hated Quicksilver so much I never touched the two sequels. I liked Reamde okay, and Ananthem was pretty interesting (but heavy). Diamond Age is a pretty okay lighter reading book. Snow Crash is okay, has some fun bits, but is pretty dated.
(Here is a SDMB thread on Fall.)
