I own both actually and can't say for sure that one is better than the other.magne is definitely noticeable on turns, as in, you can feel it grinding a trench.....but whether one holds a better edge on ice than the other, then no, I have not noticed a difference. I base my observations on traversing icy no fall zones in the alpine (backcountry).
If you have hard data, please link me by all means.
