Noda is too expensive, given the fact that the price will fall and there is no guarantee that the developers will not disappear.
AXEL has been around for a decade. They're all about data privacy and this is just one part of it (I started using their online file hosting system after I saw their work here and looked them up, it's pretty good). They're not a random group of devs that spawned out of the recesses of the internet for this one project alone.
