One thing I don't think anyone's mentioned yet is stability and accuracy. The short recurved bows I've built (bending through the handle, and 54" ntn or less) shoot really fast, but they're harder to control. That's why I like a nice marriage of both worlds- a 64-65" ntn static-handle recurved bow with short sharp-bending static tips.
I also have to say, I'm kinda obsessed with Marc's bows (yes, If there were a Marc fan club I'd run for president). I just feel like he's got a lot of things figured out so a lot of times I go off his example. He makes longer static recurves, deflex-reflex, and ALBs.
P.S. Sorry Brad, I know the post was about what's faster. I got a little off topic.
