It's not really about the overhead. The intrinsic overhead of async. is trivial, anyway. It is more about predictability & how the system is understood. Async architectures let you have simple, easy-to-understand components, but the expense of a more complex macro-control-flow.

It is not so much that one is objectively better than the other, it is just about how different people's mentality works.
