Ag-Grid Icellrendererangularcomp Vs. Agrenderercomponent: Which One Should I Use?

I'm using ag-grid-angular and need to make custom cell renderer.

In examples of ag-grid angular document, cell renderers implement ICellRendererAngularComp. But I also found some other examples implementing AgRendererComponent. So I have tried both of them and they are working clearly.

My question is, which interface should I implement to create custom cell renderer?

I cannot find any other codes that only exports these interfaces in ag-grid project like this:

export interface ICellRendererAngularComp extends ICellRenderer, AgFrameworkComponent<ICellRendererParams> {
}

...

export interface AgRendererComponent extends ICellRendererAngularComp {
}

It seems AgRendererComponent is more high-level interface, but examples in ag-grid document are using ICellRendererAngularComp... Can anyone at least tell me differences between them?
