@jber...Ether and Steemit are the only Crypo-projects who are used in real life. As we see Steemit even more then Ether. But Steemit is just distributed on 30 (or 100?) servers (Distributed proof of stake). It's probably possible for utube to manipulate this 30 delegates if steemit would get a threat. In this sence, Ethereum is much more secure but also slower.
