Actually both are good.

Everyone can choose what they like.

The more possible options to choose from, the better.

Currently I am receiving both Hive and Hive Power for my Hive Power delegations.

Receiving Hive Dollars (HBD) for Hive Power delegation would also be good, but I have not found such Hive accounts/projects so far, which would reward its Hive Power delegators that way.
