If you are unsure about what a tuple is, I wrote a brief guide for Pluralsight last year, https://www.pluralsight.com/guides/returning-consuming-tuples[^]. Something to consider if you use async/await, you can't use out with your parameters but you can return a tuple as part of the Task signature.

If one were "best", there's no reason to keep it around in the framework. You can also use tuples as out variables, which makes your question unclear to me. Can you give us two examples of what you are trying to compare?

So Tuple is a good thing. It is very useful in scenarios where you need to return multiple values from a method but do not intend to create a dedicated DTO for that sole purpose. It is not of structure type either which means it is passed by reference. I created 2 methods in my controller for testing Tuple - one for Get and other for Post.

[HttpGet]
public ActionResult TestTuple()
{
Tuple t = new Tuple("test", 123);
return View(t);
}

    \[HttpPost\]
    public ActionResult TestTuple(Tuple tuple)
    {
        return new EmptyResult();
    }

The view part is straightforward:

@model Tuple
@{
ViewBag.Title = "TestTuple";
}

@Html.BeginForm("TestTuple", "Home", FormMethod.Post){

@Html.EditorFor(m => m);  

input type="submit" value="Test Tuple"/

}
