For an ecommerce site, there was nothing special required. I used the WordPress plugin WooCommerce along with a pre-existing theme with a few modifications.
* It doesn't really offer anything over Storefront, the WooCommerce theme from Automattic -- the core developers of WooCommerce itself.
The advantage of using a theme from the actual WooCommerce developers, is that we know it will be written to the same high standard without any compatibility issues and should always be up to date with the latest version of WooCommerce.
This theme does look a little different, but nothing substantial. Certainly nothing that couldn't be achieved with some customisation of Storefront.
* It doesn't do much to set it above all the other similar looking WooCommerce sites around. It looks clean and fresh, but nothing particularly stands out.
So, I feel it is perfectly fine for someone wishing to set up a WooCommerce site with an acceptable theme quickly with little effort.
But, not so good for developers, who will most likely want to customise and, in my opinion, would be better off starting with an alternative such as Storefront.
