Shopify is the king when it comes to ecommerce and Wordpress is the king when it coms to blogging.

As Woocommerce is just an addon for Wordpress, it can't be compared to Shopify, Shopify is a complete ecommerce platform, user friendly and pretty easy to use, i'm running successful Shopify ecommerce store using the fastest Shopify theme named Plak, i don't think there is such a fast and powerful theme in Wordpress.

So in my opinion, if your main purpuse is ecommerce, so go with Shopify, but if your main purpose is blogging, go with Wordpress.
