ZenCart vs OsCommerce

[cje]

I have a request to those of you who knows ZenCart well;
what's the main difference between ZenCart and OsCommerce?

I've been taking a brief look at ZenCart and have difficult to see what's the main difference between these two e-commerce solutions.

By the way, I think both ZenCart and OsCommerce lack the abillity to build a CMS structure.

Thanks for all information that may come.

If I remember well, os-commerce need that the global register of the server (php) is setted to "on", and my server don't make this for security reasons.
So I'm working with zc.
