Can you recommend a service that makes managing Hive delegations easy?

Steemworld had a very nice interface for this, but that is for steem only.

Can you recommend services that take best care of delegations, while offering a return? In the past, I stayed away from most of these services, because I did not like not knowing who I was trusting with my delegation, or what they were doing with it. It was usually easy to spot which accounts were using delegation purely for driving profits, without a care for how they took advantage of everything.
