As someone into gridfinity the selling point for me is less of the general purpose storage , that as you point out has cheap and durable solutions available, but the ability to be tailored to quick access to specific tools. A good example of this is the original creator of gridfinity made a workstation for his dremel and all of its bits that can be popped out to go work on a project and then popped right back into its home.
