Xsite Pro for ecommerce?

What are opinions on using Xsite Pro for an ecommerce site ( digital products only) ?

I don’t know too much about Xsite pro but from looking around their site and a couple others revolving around it, I think you’d be better off using a better ecommerce system like Magento or OSCommerce or OpenCart, something along those lines

It is first time I see this Xsite Pro and we have been in ecommerce for a while. Every time I see sites like this with too much text and guaranties it make me think twice.
I think there are many more alternatives like mentioned before with addition of CS-Cart that would be our top choice at the moment.
