Which one is cheaper and which one has more powerful features?
@markhenry26 Magento has more powerful features.
But i suggest go for WooCommerce because it doesn’t take much time to set up.
I would go for Magento. Although it is a more expensive solution, it has clear advantages in the form of :
Easy integration with 3rd party software: Paypal, eBay, Mail Chimp, Google Shopping;
Intelligent filtering conditions. These are the Magento’s unique search term clouds, product tag filters and so on;
Build In product upsells and cross-sells;
Huge user community who are able to help with almost every problem you can possible have;
And if you are not satisfied with default Magento functionality, I would suggest you look at some of the extensions which can expand its default functionality.
