I don't see that TRON is the worst coin. In fact, I see TRON's success as depending on their success in integrating into the blockchain system. As a project based on a blockchain system even TRX is available on the system and interoperates between the system and external nodes, TRX will probably gain traction among the sea of existing assets. As others have said, TRON is not completely decentralized or even federated.
no one is saying Tron is a bad or worst altcoin. Maybe this altcoin has some shortcomings in some ways, but we can't say Tron is a bad altcoin just because of those shortcomings. Even the most popular altcoin currently, namely ETH, has not been able to solve the main problem, namely very high transaction fees.
I am used to people, they just bring unnecessary rivalry from nowhere. First, I wonder from the main OP why the brains behind Ethereum and Tron are rivals and the rivals both have all it takes to upgrade and make them scaled better for more rivalry and competition to be achieved, but one did not. Why is Tron then taking it gently and slowly? Well, in my understanding, projects and plans vary, and I believe that what the brains behind Tron want it to look like is what it looks like as we see it presently, and the same thing goes for Ethereum.
For the record, Ethereum will beat Tron many times over for many obvious reasons, we should keep it that way and enjoy both where we prefer them. For investment and other crypto projects, one may want to prefer Ethereum, but for sending money, one may want to prefer Tron.
