A very nice write up! Can definitely tell that you've done your due diligence on all 3 projects. MyWish does seem to be a step above Safe Haven but still doesn't solve the inheritance aspect if the inheritors aren't familiar with cryptocurrencies, wallets, private keys, etc. I like how Digipulse is currently the most flexible of the 3 options!
Upvoted and resteemed!
If you look at MyWish (https://contracts.mywish.io) today, you will see that they are ahead of all!
