I would say DigiPulse at the moment.  Some FUD has driven the price down but the project is still alive and well and the idea is solid.  They are going after the digital asset inheritance problem with an elegant p2p, anonymous, and decentralized solution.  None of which their competitors can boast (Safe Haven & MyWish).  Their beta is open and you're free to give it a test ride and go through the entire process of setting up your vault and what your inheritor will go through to retrieve your assets all without lawyers or third parties.  Platform launch is expected in July with May/June being months to watch and possibly grab some DGPT while its dirt cheap.
