it's definitely "bigger" in that the stroke is longer

I don't have direct data on the "faster" part, but it makes sense that a longer stroke has more speed potential, especially when it is coupled with a lot of supination, which is usually is. The "strike zone" may be smaller, but within that strike zone I think the 1hbh is faster.
"Free flowing" is more subjective, however, many people prefer the 1hbh because it feels more free flowing. I've never heard someone say they like the 2hbh because it is more free flowing.
