Extending Phaser classes: ES6 syntax vs Phaser.Class: differences?

[mattasaurus]

In the Phaser 3 examples we have an example extending Phaser.Scene like so (http://labs.phaser.io/edit.html?src=src\scenes\scene from class.js):

var MyScene = new Phaser.Class({

    Extends: Phaser.Scene,

    // [...]

using ES6 we might say instead:

class MyScene extends Phaser.Scene {

From what I see, I think that these are functionally very similar. But I could easily have missed or misunderstood something.

Are these the same in effect (or almost the same)? If there are differences, what are the significant differences? Is one preferred over the other (assuming ES6 is an option)?

There are quite a few ES6 examples in the Scene folder. Just look for ES6 in the filename. Like this one: http://labs.phaser.io/view.html?src=src\scenes\scene from es6 class.js

Now I feel a little silly. But thank you.

On the plus side, your guess was right
