Best open-source ecommerce software?

[beansbaxter]

I am looking for an open-source solution that is PHP/MySQL based for an ecommerce online store...I have used Zen Cart extensively and I see OS Commerce being used a lot out their on the Internet...

Which one is better? OS Commerce or Zen Cart? Is there anything else I should consider?

Thanks in advance.

zen cart is based on OSCommerce

i like zencart a lot better, especially for rolling it out for clients
