I don't know enough about tron to say much and like you I am all in on steem.
It's a good plan though. Tron seems to be growing a nice eco system and has a few good users that have joined us. I was thinking about picking up a small bit myself so might go with this.
All the information I got was from interacting with people that joined Steem because of Justin Sun. It's a nice way to learn about other cryptocurrencies. I found out that there are other platforms that employ the same staking mechanism.
When I get enough information to share, I'll drop it here.
