We (<$500k sales, 20 consumer goods product seller) self-installed Magento, Prestashop, AbanteCart, CS-Cart and Woo Commerce. Magento is the only one we eliminated. The WooCommerce site is mainly being run as a blog.

It was clear to us that managing Magento would not be worth the investment in time/money because of the complexity of seemingly simple tasks. Our only frame of reference was competing carts which were easy to implement/manage. In comparison, Magento way of doing it always was overly complicated.
