I recently had a similar decision, albeit at the entry level for each company you're comparing. In my case it was the Colnago Ace vs. the Pinarello FP Due (both 2012's). Each had 105. I liked the looks of the Colnago more but could not justify it being $500 more than the Due ($2600 vs. $2100). I don't have a problem with the looks of the Pinarello and actually after owning it for awhile really don't think it looks that radical. However, if they were both the same price I probably would have gotten the Colnago. Despite this I have no regrets whatsoever. I'm finding the FP Due to be the perfect entry level carbon bike with a stiff but smooth ride and incredibly stable handling.
