It's too early to tell for sure. Thousands of startups and companies tell us that they will use blockchain to solve almost any problem in the world, but so far there's no good working example that show how blockchain is used in some industry. Also, it's not entirely correct to compare different blockchains, because blockchain is very closely tied to its parent network, and there are lots of different project configurations - there are private and public networks, permissioned and permissionless, small network and big networks, hierarchical and peer-to-peer and so on - public and open blockchains like Bitcoin have proved themselves to be working and stable, but the same has not been proven for all those other kinds of experimental blockchains. Bitcoin has already repelled many attacks, time will tell whether other blockchains are resistant to attacks or not.
