As far as I know KSA is the most conservative country in the world. So for sure for an Expat Qatar is better to live in. But for some people, they like the way of life in KSA as well. (I heard from a friend that one of his friends who was a drunk person decided to live in Mecca. And he is telling that he found the inner peace and happy to be there for praying Kaaba and so on) Sure if you are looking for liberty, freedom and such things you shall consider Qatar better than KSA.
