Most of the Biblical differences were different in that they had a different type of character, but both (Quran and Bible) had similar characters in the story.
Biblical differences include that of: Lucifer, Serpent (the form Lucifer took to trick Adam and Eve), Earth's creation in 6 days, and the geography of Paradise explained in the Bible.
Same as the Bible, the Quran only had minor differences, but the same story. It was more like a different version of the story rather than a whole nother story.
The only Quranic differences were: Iblis, 6 spans of time for Earth's creation, Value of the Forbidden Tree, and differences in Satan's hatred and jealousy towards Adam.
Both texts had more similarities than differences.
Similarities of both texts: Creation of Man, Man and Woman, Banishment to Earth, Iblis and Lucifer (both being the devil), Creation of Earth Timeline (timeline of God's creation being created), and the Fruitful yet Forbidden Tree.
