Tour magazine recently tested 16 aero road bikes from 8 different companies. The wind tunnel test data can be found here:

(Thanks, jackmott, for locating that, and so quickly!)
Since I'm in need of a new road bike and like the looks of the new Fuji Transonic, I was interested in how well it matched up with the Cervelo S5. I therefore eyeballed the data off the curves for both bikes fitted with Zipp 404 wheels to produce the graph below:
Note that aside from the wheels, the bikes (tested w/ Tour's half-dummy) were equipped as sold by the manufacturer, which means that the Cervelo was fitted with their slick aero-topped handlebar, whereas the Fuji had round Oval bars.
Bottom line would seem to be that there's very little difference between the two bikes, except at high yaw angles (e.g., strong crosswind situation), in which case being on the Fuji means having to produce ~5 W more power to go the same speed.
