A little off topic, but I'd like to add to what @eric just said but with respect to descending as opposed to ascending, since the two usually go together unless it's a one way ride. There is a very noticeable gyroscopic effect on wheels. And it's easy to feel. Here's what I show people to demonstrate... take a front wheel with a fairly weighty rim, hold it by the skewer in your hands and spin it as fast as you can. Now, while it's spinning move it around a bit as if your leaning, turning and twisting down your favorite descent. You can feel how it wants to right itself. Now, do the same thing with a wheel with a very light rim... compared to the weighty rim, this wheel is much less forceful in it's tendency to right itself.
Now, think about that when you're on the bike. It's just one more factor that contributes to downhill stability. And there's always tradeoffs. Probably my favorite wheels for descending would be my 32 spoke Nemesis tubulars. Low profile so they don't catch as much wind as a higher profile wheel, but also having the weight of the rim far away from the hub helps create that self stabilizing effect. Are they going to be as fast as a high profile carbon rim... no. But they inspire confidence and added safety which is something to consider as well. I love my carbon rims, but I'm generally a little more cautious on descents with them.
To the OP: you have sets of both of the wheels you're asking about. If you have to ask which ones are better, what does that tell you? Constructionwise, etc., maybe, but just stick with the ones you like the most and forget what other people say. Boras all the way
