The big difference between Muslims and non-Muslims is that almost every Muslim has at least heard or read the Qur'an from start to finish once in his or her life and some Muslims are Arabs or understand Arabic perfectly, yet you do not see mass apostasy by Arabic-speaking Muslims, whereas you see mass apostasy by Christians, leaving for other religions or taking the easy way out to Atheism.

Also, the Qur'an is one of the things that attracts non-Muslims to Islam. It has been doing so before it was even completely revealed, with Umar trying to wipe out Islam to being one of its greatest warriors and leaders after hearing just a few verses from it.

It is rare to see people who become Christians citing the Bible as the reason for their conversion. That is because the Bible of today cannot be considered preserved revelation, having been through dozens if not hundreds of editors and authors.
