You can't reset your data meter after installation for a fair comparison. You have to do it after you've played both games for a while. LOTS of mobile games don't actually finish installing right away because they pick up game assets at runtime instead of making the initial install bigger. (This also makes it possible for them to do content updates without waiting for Apple's approval to release an app update.)

Now that you've been playing the games for a while, a good test would be to reset it now and then go play each game for exactly the same amount of time.
