Who is the strongest? Who is the best? I have been through a few e-Commerce solutions in my time. I have toiled at the cliff face of Actinic when it was based on Perl. I have rolled my own shopping carts in Perl and PHP. I have dallied in the dystopic realms of osCommerce and swam in the waters of Zen Cart. And finally, having tried them both, I plump for Prestashop in preference to Magento.
