Woocommerce or website erpnext?

I’m really in doubt between using woocomerce for online store or the solution delivered by ERPNEXT.
My biggest concern is with possible integration failures.
However I am facing a lot of difficulty in organizing ecommerce with erpnext.

One of the pertinent problems is with the menu, I would like to create a menu with all the categories of the products I work on. But I can only see in the bar, button for all-products.

I would also like more information about SEO, usability, speed.
Will I have to use a freight module (Brazilian post office), will it conflict with the integration?

You can configure the top bar from Website Settings. you can include additional links and take out existing ones.
