Hive account@smartsteem has a cool delegation reward payback.
I also like Hive account@steembasicincome as another system that pays back pretty well, the delegation system they use will pay out in upvotes. They also have a cool system where you can send them 1 steem and another accounts name in the memo and you both get a share in the project, that share adds you to a Upvote list. Shares can stack and some have hundreds. I like their system. Despite being called a basic income that you have to pay into, as opposed to being just enrolled for free. (; LoL. But I guess one could just write good posts on contests and get enough sponsors to make it worthwhile....
The smartsteem will just strait pay you out to your steem wallet.
