Assuming crypto is a valid store of value and you wanted to do something like time release money for a will or other purpose, those other choices don't sound like very good options. Of course you can also do the same thing with Bitshares and probably a few more platforms, so what it really all comes down to is who has the best consensus mechanism designed to make the service not die. The only problem with Ethereum is they released a coin without making a consensus mechanism and are trying to make one on the fly...
I know many people will read this and say, "hey idiots, just use a service backed by the legal system". That's a decent option if you're living in the good times of a stable country, but there's plenty of unstable countries out there.
My point is that you can use Ethereum to make an app that can "time release money for a will or other purpose" using litecoins or bitcoins or any cryptocurrency with the capabilities needed, and it doesn't need a coin to do that. But I suppose people think that Ethereum has every contingency and will never fork because it is Turing Complete and therefor perfect.
