I have used AIR Wifi (for me better than Ethernet) for a long time, USB was always a little bit inferior to AIR. Now with Win10 this has changed, now I prefer USB. If you additionally optimize the PC for USB (jplay, Fidelizer, ProcessLasso) and a good cable (I'm using an Aqvox) USB is far superior to AIR. And I don't think that AES/EBU will be better, I think it will be worse.
But for a quick test you can download Fidelizer and ProsessLasso and a demo of jplay and try it with a standard USB cable. You can even start with plain USB from jriver which is already better than AIR in my case.
Additionally USB gives you a more stable connection without white noise issues and a faster response time. Before you make any decision make sure you have configured jplay correctly for best performance with USB.
