If I were to get a true "road bike" I'd probably get the Specialized Dolce. When I was looking into getting a touring bike, I test rode pretty much every bike my LBS had. (They get a commission if they sell something they have in stock.) I had them special order my 520.
Point being, I rode Trek, I rode Giant, I rode Specialized (didn't have any Kona's) Out of all of those the Dolce was like buttah. Smooth, responsive, I felt like I was gliding. I rode the Dolce elite with carbon fork and zertz anti-vibration in the seat stays. I almost got it, then I remembered that I wanted a "touring bike."
Specialized almost got me though, and maybe someday....
Just my personal feelings though. I agree with everyone else - test ride, test ride, test ride. 
I'm not a fan of Giant. Their sizing is sooooo limited it makes it hard to find one that fits. Anyhow there are my two cents. (for what they're worth - conversion rates may vary.)
