I didn't follow Tron news but I definitely support EOS. May be because there is a lot of hype about it, may be because it has a good team. I really don't know, but my chose for today is EOS. Again, I could be wrong just because I didn't follow to much about Tron news.
There were a lot of hype within both cryptocurrencies, but I believe that only one shall deliver true development and innovation to the blockchain space. If I compare EOS vs TRON, I'd see that EOS has much more potential than TRON to become a popular smart contract platform in the future, simply because it has an outstanding development team and a supportive community. On the other hand, TRON looks like a copy of already established smart contract platforms like Ethereum and NEO. It has the same consensus algorithm as EOS (known as DPoS) which may have the same level of throughput than its competitor.
Of course, EOS had some difficulties since its launch, but I believe that's normal, to make the platform stronger and better than ever. Same thing happened to Ethereum, where there existed a lot of bugs within smart contracts, the DAO hack occurred, and many undesired situations. However, now Ethereum has grown into a strong and widely used smart contract platform for the masses. As such, I believe that EOS will improve over time to gather the attention of mainstream developers and everyday people. I must admit that the arbitration process within EOS is centralized, but with the newly proposed constitution by Dan Larimer himself, EOS could perform much better in the long run as a decentralized smart contracts platform.
One advantage that I see EOS has over TRON and even Ethereum, is that smart contracts can be frozen in case there is any bug or issue within the same. That way, the whole network would continue to operate as normal without disruptions, unlike Ethereum where a hard fork was necessary to roll-back transactions from the DAO hack. Things aside, there's only one thing which I believe that will give a fair advantage to TRON and that is the acquisition of BitTorrent by Justin Sun (TRON’s founder). Since BitTorrent has a large user base, now it can be migrated to the TRON network to expand its mainstream adoption.
Nevertheless, only time will tell us which of these platforms will prevail in the cryptocurrency market. Just my thoughts
