I am still for WORDPRESS... wordpress can handle alot of stuffs, article management, e-comment systems, membership systems etc...
Isn't Magento an eCommerce solution ? If I am not wrong WooCommerce, a WordPress plugin does pretty well in this field. But it is an eShop you are planning, I may vote for Magento that WordPress with an eCommerce plugin. Of course, WordPress is easy to manage.
I haven't really tried Magento and is still learning my way around Wordpress but based on the research that I've done recently, Wordpress is a lot more flexible when it comes into building dynamic websites and have an easier learning curve. Please guys correct me if I'm wrong as I also want to know if this is true for others.
