How is the Sikh holy book, The Guru Granth Sahib, fundamentally
different than other religious scriptures, like the Bible or the
Koran?

The Guru Granth Sahib the religious text of the Sikh's is a very interesting book, because of its interesting history, but also because of the fact that this book was written by several gurus, and was not claimed to have been inspired by any superior being. where as the Bible and the Koran both claim to have supernatural backgrounds, the Guru Granth Sahib was a compilation of hymns that describe god, written by man.
