is that 6700 or 6800 Ultegra?
I also think if you ride both for a few miles (not just around the store, or the parking lot) you will like one over the other. I like the looks of a Cervelo over the looks of a Trek any day of the week but I would never want a good looking bike that I don't LOVE to ride. People who own Trek's love them for the comfort, performance....and other things. Best wishes on your purchase, don't forget to share a pic when you decide which way to go.
