Yeah Hive has all the best devs, lots of dapps built over it as you said. Blurt is still young, lots of things still have to be straightened-out and has to settle in before a better value happens. Steem has it sown thing, being still bullish and it rides the bullishness of BTC as well its downward movements, so it is still a good option to involve one's self for investing.
I wish you more success in here, you are doing excellent.👍
