EOS will be much more centralized than Ethereum. I think both can exist, perhaps EOS makes more sense for SteemIt-like apps, while Ethereum's bread-and-butter will be financial smart contracts.

People who believe that Ethereum can be used to build a social network are seriously delusional. But EOS might not have censorship-resistance. Note how description mentions "legal files", implying that files can be censored. So can funds, if block producers are big and known, they will have to comply with laws.

So EOS is more like AWS with more crypto, while Ethereum is more like Bitcoin with smart contracts.
