As a previous owner of Look 675, Cannondale Evo HM, Felt F2, Argon Gallium Pro
Currently ride a Scott Addict SL & Focus Izalco Max. I would choose the Addict over any of the bikes I've owned by a mile.
Reason: Comfort, Stiffness, Weight, Responsive
While some of the previous bike I've owned might be a bit more comfortable, more stiff and weight less. They just don't have all 4 above combined in 1 package which the Addict offered.
