As far as I know, the EOS project today has a very non-simple blockchain, most likely it looks like a regular registry in notepad, so I think that encryption is better with ETH. The same can be said about blockchain
EOS, of course, needs to undergo upgrades, as ETH needed to do in the course of its development (now again with the Contantinople fork).
As I said in one of my replies before, I see different fields of use for ETH and EOS.
