If you've only done parking lot test rides on the Ruby, Synapse (carbon or Al), and other endurance/sportive bikes, I would take each of them out for a longer ride that involves hills. Assuming the bike shops take the time to tune the bikes to make sure they shift well and have no brake rub, you should be able to feel a difference when you accelerate and climb with these carbon bikes.
Also, if you're only 5'2", then I would think a 50 cm Trek Silque (518 ETT) is probably too big for you. Did they have the Trek Silque in a 44 or 47 for you to test ride? Could the twitchiness have been because the bike is too big or they swapped out the stem for a really short one that messed up the handling?
