I have been making some progress on Hive. It's one of the good platforms for the content writers who wish to earn crypto rewards for their content. You earn Hive dollar (which is pegged to USD) and Hive which keeps the economy on Hive. This hive can be converted into the Hive power which allows you voting rights on the platform.
This doesn't stop here. You get to stake this hive power to some of the curation accounts which reward you back with the Hive on daily or weekly basis. So In this post, I am pointing out to some of the accounts that I have tested for HP delegation.

Note: There are more accounts than the one listed here for HP delegation. Do comment if you know any specific that you have found useful.
ecency
You can search for eceny on Google and you'd be presented with a clean interface towards Hive. It's an alternative frontend to the Hive, which is available for both Desktop and Mobile. It's one of the good interface worth using if you are having problems with hive.blog and Peakd interface on your end for some reason.
Ecency does the curation and gives out the percent for your delegated stakes. I have found them to be pretty much profitable. Though some of the time the rewards may come late a day or two. You'd get the balance properly adjusted eventually. It's a good account worth delegating your stakes to. I have tried from 100 to 500 HP amount and tested for a reward. It seems like a good account worth delegating.
hodlcommunity
I like this account because they are pretty good with the timely rewards. Also they can feature your content and some of the time randomly upvote your content too. It's one good account to have your delegation. I have tested from 100 to 500 HP and they are on time with rewards. I have continued my 500 HP rewards with them with one account and I feel good when I get passive rewards especially when I can't do curation my own self. I personally recommend this account for you in case if you want to delegate your HP for passive rewards.
ocdb and curie
These two accounts are from the people who are pretty much elite or say whale accounts. The people if found any spam or any clashes on the network literally send an army of the votes to downvote you. So never mess with these two community curation accounts. They also have the downvote trail for you. On that context I'd say cleaner accounts you can follow for downvote checking. Overall I have found these two accounts giving 80% to 90% of the rewards in Hive. They are often few hours late maybe due to the server being located in US or EU probably. But pretty good accounts for giving delegation upto 500 HP.
diyhub and buidl
These two accounts are specific to the DIY niche. You may also find them curating in the homestead, agriculture and the similar other content. These would be good for hive earning from these accounts if your interest happens to be in these niche. I have realized that these two accounts are going to be pretty good for the rewards as it is giving 100 percent to the delegators. However do check on regular basis if they are active because you never know.
leo.voter and meowcurator
If you want to earn LEO for the delegation reward then you should give out your hive to these two accounts. You may find some really good conversion out of your Hive delegation from these two. leo.voter gives out pretty decent LEO amount for the delegation. Also the meowcurator is another alternative where you may find the humans curating the LEO feed. If you are active in the Leofinance community then it's worth investing your HP into these accounts.
List doesn't end here.
You have plenty of options out there to choose from when it comes to the delegation accounts. The few listed here are some of the good accounts that you would find useful for your usecase. I would say these are some of the good accounts worth trying and also worth investing your HP for the passive rewards.
Are you delegating your Hive Power? Which are some of the accounts that you're using?
