This is the time I wish I can have a remind-me function like Reddit here on Steemit to tell myself how stupid I am to not deep dive more into the list you recommended.

Steem is the one I am most confident with not only because it is one of the few already-use applications with active users, but also the strong community and the upcoming Smart Media Tokens.

The other one would be Lisk. Simply because I think JS is the most adopted programming language on the web. And a Dapps platform integrated with JS seems to be the one to be succeeded as it seems to be easily adopted by the people.
