You pretty much share the same outlook I have on STEEM and SMTs. EOS is going to do great things but STEEM has a much more robust ecosystem. One could even make another social media like ONO. But they have nothing like @dlive @musing @fundition and many other projects.
It's great if you can take a look at my ideas about promoting STEEM at the current moment. (Basically I think most people are going at it in the wrong way): https://steemit.com/steem/@vimukthi/a-radically-different-and-more-effective-way-to-promote-steem-that-can-deliver-much-better-results
