Custum code in functions.php

Hello,

I have 2 different codes in use on different Enfold child themes in my functions.php that add Clicky Analytics code to my website.

On some of my websites I use this code:

function alwin_clicky_analytics_footer(){
?>
<script src=”//static.getclicky.com/xxxxxxxx.js”></script>
<?php
}
add_action(‘wp_head, ‘alwin_clicky_analytics_footer’);

And on some websites I use this:

function clicky_analytics_header(){
?>
<script type="text/javascript">
<script src="//static.getclicky.com/xxxxxxxx.js"></script>
</script>
<?php
}
add_action('wp_head', 'clicky_analytics_header');

They both seem to work fine. I just like to know if one may be better then the other?
