RME - Madiface USB vs. Babyface???

I can score good pricing on any of these right now. Need a new small portable interface. It will be either or the other.



There are barely any comparisons online of these units. So I'm kinda sitting in the middle at the moment.



So what do you think?



Madiface USB or Babyface?



USB 3 or Texas Instrument Firewire??
