Fast, light. Great for climbing and stable descent.

These are simply amazing wheels.
They handle far better than my Zipp 101s almost every situation: especially in crosswinds and climbing. I put on 9800ft of climbing in my first ride. They spin up fast on an incline and are extremely stable on fast descents with high crosswinds. I've rode the same/similar hills with the Zipp aluminum and other carbon wheels (HED Jet) and experience stability issues on fast descent (> 40MPH).
The published weight of the wheels are actually accurate when I put them on a scale. They are one of the lightest clincher alloy wheels on the market today.
The Dura Ace hubs are very smooth and quiet. Unlike other hubs (talking to you Chris King), they don't sound like a swarm of busy bees coming at you. Quiet is good: less rotation energy converted to sound energy (although negligible). They also look like they require less maintenance when compared to other hubs.
The quality of the factory build is great. They almost rival some of the hand built wheels I've purchased.
I plan to ride these at Ironman Coeur d'Alene. Its a hilly course with high crosswinds at some of the passes. I rode on carbon aero wheels last year and swore carbon off after the same race because of weight and crosswind handling. Gram for gram, I cannot find a carbon clincher wheel that's lighter on outer edge of the wheels than an alloy wheel. Weight on the lateral edges is where you're required the most power to spin up to speed. A hilly course is essentially a course where you're constantly required to spin up again and again.
I've also stopped reading white papers published by manufacturer's marketing department. The Aero numbers they publish are typically junk. I'll be the contrarian: I'll take weight advantage on wheels over aero advantage any day. They're tested with wind tunnel conditions that a real rider will rarely encounter over the course of an entire race. (Like: Direction of wind staying constant to maximize the drag/yaw numbers. Or worse: at wind speeds a typical rider won't achieve in order to show benefit). Shimano products are a "sleeper" in that sense. No bling marketing, but a very solid performer. I'll take these wheels over wheels I've paid over twice as much for.
