But isn't Magento versus WooCommerce like comparing a mosquito to an elephant? We've been wormig with Drupal Kickstart Commerce for a couple of commerce websites and it's been a terrible experience. It's without a doubt the worst CMS I've ever come accross. Drupal in itself is something of a beast, but with KC it just maken you want to cry.
SAAS solutions seem the most elegant, but we don't want to become a reseller and want to retain fill control for oud customers.
Prestashop looks interesting and not as bloated as Magento.
