I do like Steem but its is all just flavours of the same dapp - post, curate and reward in steem.
EOS allows any type of dapp to be built. How will you build an exchange using Steem, how can you do smart contracts, how do you create your own viable token linked to your dapp, how would you build an Uber style service. If you look at any list of potential applications for blockchain, Steem is only a good match for a few.
