The correct answer is - it is more precise.
The large scale maps that show smaller portions of the Earth's surface have the advantage over the small scale maps because they are more accurate. The difference grows with the scale number difference, the smaller it is, the more accurate it is, the bigger it is the less accurate it is. For example, if a neighborhood is shown on a map, than it will be very precise and will capture the exact picture of the area, but if the whole planet is represented, than the accuracy will be much lesser, and that will be especially evident with the places that a further away from the equator.
