What do you mean by "integrates it into their search results"? Hipmunk's killer feature is the ability to easily visualize the flight in terms of the time you leave, the time you arrive and the time spent at various intermediate locations. It becomes more useful when there are no nonstop flights. Google is taking a different approach with their UI, which is fine. In terms of whether I'd use google or hipmunk to search for flights in the future, I'd say that it depends on what my priorities are for that particular flight.
