I'm new around here and I can't comment about technical stuff because I only know little things about this platform and I don't use any of the others that you mentioned, but I can say that Hive have a lot of potential.

The problem here is that most of the users expect to earn lots of money with little effort and it doesn't work like that. If you wanna earn good rewards, you need to work hard posting good content and engaging with other users and communities. That way you are helping Hive with its principal goal that is to be a community based content platform and you build a good community yourself that can bring you good rewards.
