Long answer: practically speaking, it doesn't matter if it's better or not, because there are few consumer-ish FireWire models to choose from, and perhaps fewer that offer both protocols for comparison.

Any discussion of connection protocols will at some point involve data clock control and therefore jitter. Partly due to USB's popularity (it's cheaper to implement, but not tremendously so) we now know that USB offers the possibility of asynchronous control, which is conceptually simple because instead of trying to reduce jitter between two components with differing clocks, asynchronous control essentially says, "hey, let's forget the clock altogether on one component" --- so with one clock only, jitter's pretty much wiped out.

FYI, FireWire is "universal" to PCs too, common on models that aren't bottom-feeders, it's just that PC owners don't know what the heck it's for. (I kid.)

And the Duet was just replaced. The new model uses instead ... USB.
