Just because a lot of competitors have emerged, doesn't mean that they will win - they are all pretty bad, centralized and vulnerable, just like Ethereum. Smart contracts are still only a proof-of-concept, so by the time they will be useful, Bitcoin will probably get them and will kill all the Ethereum-like coins.
nothing that's around now will beat it. like you say they're all shit. but someone somewhere will unveil something that destroys them all. a huge amount is being learnt every second and the people working on stuff like ethereum are now anchored to a lumbering beast, not something scratch built.
