In terms of popularity, you may be right. Steemit is the one who is known because it was born years ahead of the hive. Although I don't think the readers on hive are incomparable with steem. I mean no offense here but I'm on steem sometimes and I noticed the engagement there is way different from hive. Also, steem is not that strict in terms of writing. I won't say they're better than hive or hive is better than steem. I'm just talking about now because in the future steem will be gone because of hive.
