They are not the same fit if you cannot reach the brakes on one of them. That one is not a good fit. They can put shims in, but why not get a bike that fits right since you are getting a new one? Ask the bike shop about short-reach brake levers if you really want that bike. Otherwise go with the one that fits better. Sora is better than Tiagra, but personally I'd keep looking for a bike that fits that has 105 components. 105s will last alot longer and cause you fewer clicky-clacky annoyances than Sora or Tiagra. On the positive side, you can easily upgrade the components later if the frame is right.
