Problem with Islam is that it is still heavily used as a law-book, and is written to be used as a law-book.
In a world with nuclear weapons, internet, computer-farms capable of crunching trillions of equations a second, having a thousand year old rules is dangerous. Just look at America with the second amendment. The law-writers didn't imagine assault rifles capable of hundres of rounds per minute to be sold on street corners. They thought it would primarily be for musket-users, who took a minute to reload after each shot.
Christianity has much less laws for how society should be than the Qur'an. The bible wasn't written by a rising empire that nearly controlled every nation with a coast in the Mediterranean. If it was it probably would have had more of that too.
Not that I'm a fan of any Abrahamic religion, but from a intrusiveness point of view, Christianity is less overbearing, and protestantism has acquired the sensibility morals of "labor gets you to heaven" instead of "Blasphemy gets you to the grave", or in the case of Catholicism, "Pay for your sins to the pope for instant access to heaven" .
Christian countries have done a lot of bad through the ages, but the reforms that have been made the last century have given us one of the few places in the world where order reigns. That would not have been the case if we had a extremely conservative religion that mingled with what we are allowed to say, research, being judged for, and so on and so forth. Certain Muslim nations have that too, but usually they are very, very inspired by the west. It's not impossible to have the order of the west, its not really funded by religion. Corruption is the primary nemesis of order. Corruption and apathy.
One of my bigger problems with Islam is the "Inshallah", if god wills it. It's a defeatist and apathetic point of view that until the Arab spring have caused most Arab citizens to not do anything about terrible life conditions. Also, when the laws ruling the land are given down by God himself, its kind of hard to try and change something for the better even if you know it could be better. Education is nice, you can with it notice how your leaders are not walking the walk when talking the talk. The rich and powerful in Muslim societies are some of the most despicable people you can come across, because they abuse the religion for their own gain.
