Is it better to use `$this` or to avoid it when calling another method in the same PHP class?

When calling a method in the same class from within another method, is it better to use $this or to avoid it, or is there no difference at all?

One benefit I can see with using $this is that it is explicit. For example:

class A {
  public function a() {
    $x = $this->b();// or $x = b()
  }

  public function b() {
    //
  }
}

Unlike other languages, like C++ and C# and Java, to access a member property of a class in PHP, you must always use $this as a qualifier upon the property.

For example:

class Test {
    public $myVariable;

    public function __construct($a) {
        $this->myVariable = $a;
        // $myVariable doesn't exist, must always use $this-><*>
    }
}
