What is the primary reason for the perceived visual difference between the Sun and distant stars?

Distance

The perceived difference in apparent brightness and size is overwhelmingly due to distance. The Sun is extremely close at 8.3 light-minutes, causing it to appear bright and resolved as a disk, whereas distant stars appear as faint points of light.
