Firstly, they are NOT migrants, they are refugees. Secondly, do you have any idea why they are fleeing and what the civil war in Syria is about? It is a religious war. Those war between Shia Muslims and Sunni Muslims. The Shias are the ones fleeing. So would they go to other Sunni dominated countries like Saudi, Kuwait etc for asylum? And risk starting another war?
They are fleeing to countries that don’t care what type of Muslims they are.
