Come Drupal 7, you'll want to use drupal_function_exists() specifically so that it can lazy-load the function if needed. I suppose that's a strike in favor of using function_exists() for now so that your logic is already setup for that.
Right ... For D6 and below, module_invoke() does the if (function_exists()) for you. Some people prefer that pattern.
