Which of these two scenario's is best practice in ASP.NET MVC?

1 Post to self

In the view you use

using (Html.BeginForm) {
    ...
}

And in the controller you have

    [HttpGet]
    public ActionResult Edit(int id)

    [HttpPost]
    public ActionResult Edit(EditModel model)

2 Post from Edit to Save

In the view you use

using (Html.BeginForm("Save", "ControllerName")) {

And in the controller you have

    [HttpGet]
    public ActionResult Edit(int id)

    [HttpPost]
    public ActionResult Save(EditModel model)

Summary

I can see the benefits of each of these, the former gives you a more restful style, with the same address being used in conjunction with the correct HTTP verb (GET, POST, PUT, DELETE and so on). The latter has a URL schema that makes each address very specific.

Which is the correct way to do this?
