I'm sold on time aligned and phase coherent speakers. With that said, I'm biased for the Vandersteen. It also allows for fine tuning of the bass (as Sean points out above) and it's much less money for just as well built but more accurate speaker.
The ribbon tweeter and dual ported woofers would scare me away immediately. I have never heard ribbons and dynamic drivers ever blend correctly to the point where I didn't think you had timing issues.
You may not prefer the Vandersteen, which is of course fine. A lot of Audiophiles do not get excited over truly accurate designs. The are use to hearing colorations and the tweeters sound arriving way before the rest of the speaker giving that "Illusion" of transparency.
