A accurate answer would require more info, what USB? usb2, usb3 or usb3.1. Also the host controller chip set effects the speed. Looking at your specs I would say a eSATA is going to be the faster with your equipment.

The best answer I can give is I have both and have always had much better transfer rates using eSata than USB 3.0.
