I’m not sure there is a definite answer to this.
More than anything, rewards are probably dependent on quality of content than what specific platform used to post it on the Steem blockchain.
I think Steemhunt is. I would have said Musing but Musing is no longer upvoting posts so I think Steemhunt is more profitable.
Currently it has to be @steemhunt. Quality hunts and comments earn a nice portion of the prize pool each day. Plus, you'll earn steemhunt smt tokens for your efforts. I hope this was helpful enoughand good luck!
Looking out for Consistent and Continuous payouts... Congratulations! You are at the right place. "Musing" will never overlook Quality Posts made by a Steem user. You will definitely get paid for Prompt Answers and Good Questions. CAUTION! Your rewards are not determined on the bases of the upvote's your posts receive but the Relevancy of your posts. At the beginning you can get paid from 0.10$ to anywhere between 10-80$ and remember that Musing will never overlook a Quality Post from any of its users. Consistency and Quality of Posts is the Key for Rewards on the Steem Blockchain.
For starters I agree with @sweven as Musing is great for starters. I tried early on when I started out to post on Steemit and then I had a lack of followers so each post I made earnt only some amount and so one day after a long hiatus, I decided to just try and gave musing a shot. One day, I got around 1.40 usd for a question I answered and after reading a book about blockchains, it got me really excited. I just keep writing answers initially and at that time at first I was also on steemhunt platform but it was pretty difficult for me to at first post a lot of the new products as you need to be really careful about what you posted and it is not easy to find new products. Musing however, is a place where as long as you write a good answer which is of good quality, then there is a chance you may get upvoted. I rose my reputation a lot many thanks to Musing. From November till the first week of January I spend a lot of my free time just writing answers here and I could see my reputation rising so fast till now level 62 and moving to 63 very soon.
I also earn around 500 steem power and close to 500 steem just from Musing alone and have cashed out a lot of the steem to pay for stuff like petrol and all those. Musing has done something great for people like me who now believe more in the steem blockchain and the future where everyone has a chance to at least earn something, like a universal income.
