This is the MaNI show, he is currently the best active developer in crypto. Evan Duffield is more an advisor now with an anonymous developer supporting Dash. Vitalik Buterin is mainly involved in presentations and not doing as much active development. The rest of the coins are a marketing show, people know these coins are scams but they don't give a fuck as long as they making money.

MaNI is heading up blockchain development for real. Just no one knows it yet outside the community.
