Wheels? (I know nothing about them, so hopefully someone else will chime in.) Gearing? How long were your test rides? Did you get some hills in?
What do you see yourself on?

They're both really nice bikes, and if they're both carbon and the component specs are the same, and they fit...it just comes down to what you're willing to spend. And yes, in this case, you're allowed to be swayed by silly things like color.
