I think you did a pretty good job of summing up Durant's writing - if not his style, then his perspective on his work. Durant was unashamedly subjective (one needs only read his essay "Shameless Worship of Heroes" to see that).
As Durant wrote in "Book Review" on October 6, 1963, in a response to a negative review: "In reviewing our 'Age of Louis XIV' J.H. Plumb charges us with a tendency to'personify processes and events.' This is true. We believe that the in the last hundred years history has been too depersonalized, and that statistics have replaced men in the story of mankind."
