I got to try a BW 2014 with these switches at a trade show today, briefly, but I knew what to feel for. From my very subjective test, I think that it indeed does have shorter travel before actuation than MX blue and less hysteresis, at the expense of more resistance on the rebound right before it tops up. The difference to modern Cherry MX Blue is very subtle, though. I find there to be more difference between modern and vintage Cherry MX blue.
One interesting detail, however is that an unpressed key has less play side to side than Cherry MX, which means that the key don't rattle as much. I didn't find it to be sturdier when pressed, though.
I knew Razer was going to be there. I kick myself for forgetting to bring my Ducky keychain with a modern MX blue on it, which I was supposed to, or I would have been able to do a much better comparison.
