Exactly what I said - they're totally different. Just because two bikes are both ss/fg doesn't make them anything alike.
They're made for different types of riding. The Specialized has fenders (and some dumb coffee cup holder on the handle bars) and is set up a lot more like a touring bike than a track bike, while the two Orbeas at the bottom have tighter geo, no bottle mounts and are a lot more "track" oriented.
