Why Quran mentions the story of Yusuf as the best of stories?

In the second ayah of Surah Yusuf is: > **نَحْنُ نَقُصُّ عَلَيْكَ أَحْسَنَ الْقَصَصِ بِمَا أَوْحَيْنَا إِلَيْكَ هَٰذَا الْقُرْآنَ** > **We relate to you, [O Muhammad], the best of stories in what We have revealed to you of this Qur'an** I want to know what does it mean to be *the best of stories*? What features does it have that makes it the best? And is it considered to be better than the stories and novels written by humans too? (considering the features that makes it the best from Quran's viewpoint)
