Shopify vs Volusion?

I am going to be selling clothing and don't plan on making more than 5k in the first couple of months. Volusion seems like the most reasonable way to go because of pricing but not sure.

We have our own credit card service provider that will give us better rates than shopify but shopify still charges the 1% if we don't user their service for payment. The more I read the more I don't know what to choose.

Please help and thank you!
