I have come to the realization that the explanations for how airfoils work given in most high school level books are somewhere between "useless" and "maliciously misleading". I have been going through a few books which talk about circulation and down wash and vortex shedding and am only now starting to develop a (somewhat) coherent understanding of how lift works. Here's my question:-
In what way are the lifting mechanisms of these airfoils different:-

I understand that all four of these cross sections will generate vortices that are shed downwards, but what is the qualitative difference between them?
