Be sure you are comparing apples to apples in terms of the brakes, derailleurs, and drivetrain, as this is where manufacturers make choices to meet a given price point. It may not matter but if you decide to upgrade components later it will cost you more than to get a higher grade model with them installed by the factory. In terms of reach there is no need to stay with the factory installed stem and changing to one that is longer or shorter may make a great deal of difference in riding comfort.
Something I like very much about Specialized is their incredibly broad range of bike families with very different frame geometry choices for their road bikes. Giant and Trek are much larger companies but they do not come close to offering this range.
