Canyon Endurace CF 8.0 Di2 or Bianchi Intenso Ultegra

Buying question. Both bikes are around similar price. I can get the Bianchi with upgraded wheels Mavic Ksyrium UST. I usually ride 20-60 miles. I love the look of the Bianchi. Sadly i also find myself addicted to my average speeds of many routes. So if there was any discernible difference in the speed of the two bikes it would make a difference to the decision.
