Recommendations for delegating my hive power.

I am relatively new to this hive eco system. There are many well established teams working on good blockchain projects and hive eco system based project.

Often those group reward the people who delegate hive power. Its wise to not to delegate all our hive power to only one community.

Kindly suggest the best community with very good project to whom i can delegate my hive power. I am planning to delegate 25% x 4. "leo.voter", ecency" are couple of good community to delegate our hive power; however, i am looking for more options. Kindly advise if there is any other ways i can contribute to the hive community?

Thanks for all your support and thanks in advance for all your recommendations.!!
