I've owned both. They are both nice bikes, but the Trek is slightly lighter, and just feels "livelier" to me. My Trek, which I still own and ride regularly, is equipped with Campy components and Brooks saddle. That may be part of the reason I prefer it.
The guy who bought the Super Sport has it stripped and is threatening to make a single speed out of it. I would not have sold it to him if I had thought he would ruin it that way.
