It really depends on which forum you ask. Triathaletes love them, road cyclists not so much.

I personally don't like them because they're severely affected by crosswinds. You'll find yourself constantly minding your steering on a day with wind.

Also, these wheels are never perfectly true coming out of the setting mold from the factory and due to the nature of them, that's the way they'll stay FOREVER.
The same goes for both the modern carbon monocoque ones and vintage carbon composite ones. And all makes from FFWD to Zipp and in between.
