I haven't read any of these, though I bought God's War last year based on recommendations around the place. It and Ancillary Justice are the clear leaders on both sites, with the latter scoring significantly ahead on reader appreciation. Publication date doesn't seem to be a factor - Ancillary Justice appears to have been the most recently published of any of them. Note that it has also put on 100 Goodreads users (and 12 from LibraryThing) since last week.
