What are the positive and negative aspects of using Template Engines compared to directly embedding variables in PHP templates?

Template Engines offer a more organized and structured way to manage templates by separating the presentation layer from the business logic. This can make the code more readable and maintainable. However, using Template Engines can introduce an extra layer of complexity and may slow down the rendering process compared to directly embedding variables in PHP templates. 

```php
// Directly embedding variables in PHP templates
$name = "John Doe";
echo "<h1>Hello, $name!</h1>";
```

```php
// Using Template Engine (Twig)
$loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
$twig = new \Twig\Environment($loader);

$template = $twig->load('hello.twig');
echo $template->render(['name' => 'John Doe']);
```

In this example, we can see how directly embedding variables in PHP templates is straightforward and simple. However, using a Template Engine like Twig provides a more structured approach to template management, allowing for better separation of concerns.
