Which is better. USB interface or mixer?

[Bigfoot]

I'm a newbie to JamKazam and stuck in the analog world. I'm a drummer looking to jam with my band mates that moved away. I would like to know which is better a USB interface or a USB mixer. I currently using a Yamaha MG166CX analog mixer. Would it be better to connect that to a USB interface of get a USB mixer. I'm looking at Focusrite, M-Audio or Prosonus interfaces or a Mackie ProFX10V3. Any input or suggestions would be wonderful.

Thanks,
