TRON can be a good cryptocurrency if it delivers constant development and innovation. Since both TRON and EOS are nearly starting to blossom, there isn't a solid infrastructure for them yet. Comparing both cryptocurrencies, I'd say that EOS has more potential than TRON to develop into a solid smart contract platform for the masses. Still, I believe that it's too early to tell whenever EOS or TRON will prevail in the long run.

There will be people that will support TRON, whereas others will support EOS. I guess that it's only a matter of choice or preference whenever individuals want to use one blockchain from another. Despite this, it wouldn't hurt investing into both coins for the next bull market run. Just my opinion
