One advantage for me, is that systems like this let me think only about relationships. This is particularly good when designing, or exploring how to think about an existing system. So for me, I get into a flow state, just connecting the dots logically. Even better: I can adjust the diagram just by adjusting the relationships.

Miro and others, I am always thinking visually. It's another step removed from the real thought process.

As you point out, these systems sometimes produce difficult to read diagrams. For particularly important communications, I will re-draw these in draw.io, or a similar sort of tool. But then I am thinking more about presentation, rather than relationship design and the tool is better for the job.
