Use static or non-static methods with add_action hooks?

Hi,

what do you feel is better style or better practice to hook into WP actions?

Using dynamic Classes/Methods to hook into actions or using static Classes/Methods?

Version A, dynamically:

new MetaboxPost();
class MetaboxPost
{
    private $id            = 'plugin_metbox_name';
    private $title         = 'Meine Metabox';
    private $callback      = [ $this, 'render_metabox' ];
    private $screens       = ['post','event'];
    private $position      = 'side';
    private $priority      = 'low';

    function __construct( )
    {
        add_action( 'add_meta_boxes', [ $this, 'add_meta_box' ] );
    }

    public function add_metabox()
    {
        add_meta_box( $this->id, $this->title, $this->callback, $this->screens, $this->position, $this->priority );
}

    public function render_metabox()
    {
        echo "<h1>My Metabox HTML</h1>";
}
}

Version B, statically:

add_action( 'add_meta_boxes', ['MyMetaBox', 'add_metabox'] );
class MyMetaBox
{
    private static $ID              = 'my_metabox_id';
    private static $title           = 'My Metabox Title';
    private static $render_callback = ['MyMetaBox', 'render_metabox'];
    private static $show_on_screens = [ 'post' ];
    private static $position        = 'side';
    private static $priority        = 'default';

    public static function add_metabox()
    {   
        add_meta_box( self::$ID, self::$title, self::$render_callback, self::$show_on_screens, self::$position, self::$priority );
    }

    public static function render_metabox()
    {
        echo "<h1>My Metabox HTML</h1>";
    }
}

I feel like Version A creates a more "closes within itself" organization of code, but it kinda annoys me that I have to new construct an Object just to hook into the actions.
