wp function get_comments（）VS WP_Comment_Query

Question

simple question on better method- get_comments() VS WP_Comment_Query:

Which is a better method to echo out comment content (as far as speed, security)?

in both cases:

$args = array(
'meta_value' => 'tagline111'
);

This:

$comments = get_comments( $args );
foreach( $comments as $comment ) }
   echo $comment->comment_content;
}

OR

$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );

foreach ( $comments as $comment ) {
    echo '<p>' . $comment->comment_content . '</p>';
}

Answer 1

get_comments() uses WP_Comment_Query.

The function definition for get_comments() is in /wp-includes/comment.php:

function get_comments( $args = '' ) {
    $query = new WP_Comment_Query;
    return $query->query( $args );
}
