Woocommerce template overrides

Hi all,

Was just wondering what the best method of customizing woocommerce templates.

For example if I wanted to remove the breadcrumbs off each page what is a better method of removing them. I can either use functions to achieve the customisation I wish or edit the template files. I have to edit the class names within the templates to use my own styles but removing stuff like the product page sorting, What do you do Add a hook or remove the action from the template file.

Example 1. Add a hook

remove_action( 'woocommerce_before_main_content','woocommerce_breadcrumb', 20, 0); //Remove Woocommerce Breadcrumbs

Example 2. Remove the action from the template file

<?php
/**
* woocommerce_before_main_content hook
* @hooked woocommerce_output_content_wrapper - 10 (outputs opening divs for the content)
* @hooked woocommerce_breadcrumb - 20
*/
do_action( 'woocommerce_before_main_content' );
?>
