I'm not the original reviewer, but I've seen both. Helen is at the very least a few years younger than Ada: Ada is over 30, just how much over, hard for me to say. Helen has a small natural top, whereas Ada is enhanced, I think, though tastefully done. I think Helen is prettier, personally. Ada is a real pro. Helen has a bit more of a GF vibe - though I saw her sometime in the fall and things may have changed as she got more experience at NYAW.
