Haven't read them all. Of the ones I've read:

Axiomatic (best, collection of short stories)

Permutation City

Distress (contains 'sufficiently advanced' biotechnology that amazingly did not piss me off)

Diaspora

<Edge of what I'd wholeheartedly recommend>

Schild's Ladder

Incandescence

Quarantine (I found it nearly unreadable)

I suspect he's one of those authors that everyone agrees one of his books is great but nobody can agree on which one...

EDIT: I find myself seriously considering the possibility that Diaspora is in the future of Permutation City...
