Its a good comparison but I think its better to compare both on those coins that perform the same function as Monero and Steem. If I am going to invest on a privacy coin, I would consider Monero but I also want to see a comparison on other privacy coins like ZCash, Verge, Nav or DeepOnion to see which is better not on a social media coin or masternode coin, same with Steem. Please make it happen.
