There's no way to sugarcoat this - Tron is a massive, $1.5 billion project, hovering in and around the top 15. Meanwhile, Steem is a failing project that has dropped from the top 10 to barely hanging on to top 100. Indeed, were it not for the Tron acquisition rumours, it'd have dropped out EOY 2019. I have noticed way overinflated opinion of Steem by bagholders, and its frankly delusional. In the wide crypto community, Steem is universally thought of as a once promising project that is failing through mismanagement and poor development. So, yeah, the answer is Tron >>>>>>> Steem, it's not even close.

Steem will be integrated intro Tron, though the timing and nature of it remains uncertain. I bet it's going to take a couple of years, but they'll figure it out. I'm not entirely familiar with Tron, but one thing's for sure, they have an order of magnitude more developers than Steemit Inc ever did.
