I / O completion port vs QueueUserApc?

Question

On Windows, there are two ways to insert work items to avoid too many threads:

Tools 1: Use IOCP;

Tool 2: Use QueueUserApc.

However, tool 1 is much more complicated than tool 2.

So my question is: what are the benefits of funds 1 relative to the values of funds 2?
