@wxbull for what it is worth, my first bike was a Specialized Sectur 2010 model. Last year I switched to a Trek Emonda SL5. I had been considering the Specialized Roubaix and the Trek Domane. However, after riding demonstration models of both a Domane and an Emonda over two separate weekends I found that the Emonda suited me well. Furthermore, I found I could ride it for a good distance (50 miles) without any discomfort.
My feeling is that Specialized and Trek are two good brands making good bikes. What swayed me to Trek is the service, time patients and advice I was given by Trek Coventry.
I agree with Ian, buy the bikes that suit you best and do so buy going to a good LBS.
Good luck.
