Hell no. FireWire will give far better performance than USB2 because there's no host CPU overhead. USB2 will invariably get you pops and lost samples sooner or later. FireWire supports device-initiated DMA and isochronous mode managed entirely by the controller. That's why the devices cost more. Native USB3 devices have many of the advantages of FireWire, but it has to be a native USB3 device connected to a USB3 port - if either end is USB2 you lose the advantages.
