I'm far from a performance expert, but my impression is:

It shows the call paths to the functions and what part each path took, that's not so obvious from the typical table. On the other hand, finding functions that are called quite a lot all over the place and add up is easier in the table, so it's not become useless.

The latter can be accomplished with inverted flame graphs (sometimes called icicle graphs) which show the call stack inverted

Indeed, you want alternative views depending on what sort of profile or question about it you have -- with toggles in the GUI.
