One Product Shop - Shopify Or Woocommerce

Hello, I recently found a nice product that I would like to build a site on and sell, I was wondering which of the 2 options would be better to make the site with. I have the time and I am quite interested in a fast loading site too. Please suggest your answers and any alternatives, thanks.

I suggest Shopify, it already has everything you need to sell online. With WooCommerce, you first need to have a WordPress site before you can install this plugin then setup a store.

I agree with the @ContentWriter, also. You have free access to shopify for a couple of days before you decide on buying it's services.
