Replying to Naxo NX-21

The new binding from Naxo is said to be tougher and more reliable than the old ones, yet I'm stuck wondering wheter to go naxo or traditional bindings. I certainly want to be able to climb/walk more comfortable, but on the other side I would still like to ski downhill. Evidently the downhill part is what skiing is all about, still I can't make the decision.

Do you have any arguments for making the choice?
Will I have to give up some of the pleasures of riding when choosing the Naxo?
