Neither.

Explanation:

A star's relative brightness depends on its distance from us. A small star close to us can appear to be much brighter than a large star far away. For example, imagine a 10 watt light bulb 10 feet away and a second 100 watt light bulb 1000 feet away. The ten watt light bulb will appear to be brighter even though the bulb further away is actually brighter.
