Well, if you're buying it for "HER", then buy the one that she's the most comfortable on. Have her test ride both AGAIN, and decide which just "Feels" better. It's definately subjective.
You are right that for the same price, there are little differences between the two bikes. Giant's are spec'd a tiny bit better, since they have their own factory, whereas Specialized has their frames made by "others" most likely Giant as well.
Both are good bikes, but remember, if she's not comfortable, she won't ride!
