The Fuji has a carbon uni-stay seat stay so maybe that makes it feel a little less aggressive?
Without doing any research I'm going to guess that the Roubaix has a sloping top tube and taller head tube. This puts the rider in a lesser aggressive position than the CAAD with a shorter head tube.
The Roubaix is still considered a racer (someone correct me if I'm wrong) but it is more suited to rougher roads at longer distances.
