I doubt that any are more secure than any of the others. All of them are only as secure as the WEAKEST link in the chain. Security is usually dependent upon human access and, like all other things human, security is only as good as the people who maintain the security. Witness the hacking of Experion, TRW, Walmart, etc. all of which had excellent security, but were compromised by humans failing to maintain the security.
As for maintaining value, there is NOTHING of value backing up any of the cryptocurrencies. All there is are electrons which are essentially worthless. Real currencies are tied to something of value, like gold, silver, or other assets backed by governments. Net result is a wildly fluctuating market that can be manipulated at will by those with money, essentially a Ponzi scheme.
None of them. Because they are not backed by Assets. They only increase or decrease in perceived value, when people get tired of them they will all revert to the value they started out as which was zero. You would be better off trading currencies. Currencies have the the countries assets.
Just my tuppence worth.
