Using Graphics API vs Game Objects

When should we use Graphics DrawMesh/RenderMesh instead of gameobjects ?

I just tried making my prefab with one GameObject then using code to loop through mesh/material pairs and called the Graphics API to render the “child objects”. Which i have to say makes it quite a bit cleaner in some respects.

But when should you use one over the other, is the Graphics API technically more performant since we don’t have to instantiate game objects? How / when are people using that api?

In most cases, GameObjects are created in the editor, whereas DrawMesh is used for runtime (or for instanced rendering).
