You didn't mention Magneto, Prestashop ir WooCommerce in your comment.

Shopify's core product is much better than Magneto and WooCommerce. (I don't have experience with Prestashop.)

Example: Shopify sends abandoned cart emails by default. With Magento you can't even see what items are in carts in the core product.

I used all of them and it’s really no comparison. Shopify is leagues ahead of them - for non-tech-savvy users and developers alike in my opinion.
