Best practice: "path_to_theme()" or "$GLOBALS['theme_path']" ?

Some developers use a different method each to call scripts for instance.

So there are two ways:

drupal_add_js("/" . path_to_theme() . '/scripts/myscript.js');
drupal_add_js($GLOBALS['theme_path'].'/scripts/myscript.js')

We were told the second one ($GLOBALS) is rather unpredictable. Is that right?

What is the best practice to call these kind of scripts anyway?
