Title in View or in Controller [SOLVED]

Hello all,
I wonder what is the best way to display the Title tag.

Is it better to display it in the View or in the Controller?

Controller Example

PHP Code:

$data = [
    'meta_title' => "Blog Post ".$post_name,
];

return view('my-view', $data); 


PHP Code:

<?php if(isset($meta_title) && !empty($meta_title)): ?>
    <?= '<title>'.esc($meta_title).'</title>'; ?>
<?php endif; ?>

But I wonder if it's better to fill in the Title tags in the Views with renderSection

PHP Code:

<title><?= $this->renderSection('title') ?></title> 


PHP Code:

<?= $this->section('title') ?> Blog Post <?= esc($post_name); ?> <?= $this->endSection() ?>

What is the best option?

Thank you in advance for your answer.
