I might prefer ETH, the development of technology within ETH is more pronounced and on the other hand TRON seems less developed, this is seen from the price and use of blockchain technology, people prefer to use ETH rather than TRON.
That's how it should be, the ecosystem on the Ethereum network is bigger than on the Tron network, people only use the tron network for the delivery of Tron (TRX) itself and also USDT, the rest are unmanaged projects. We can see a comparison of DApps running on the two networks from DappRadar at the following link:
[1] Tron Network -
[2] Ethereum Network.
From DappRadar's ranking report, we can see that only SunSwap and JustLend projects have volume above 1M, the rest are below that value. In contrast to Dappradar's report on the Ethereum ecosystem, where the average project has a volume of over 1M, some even reach 1B, namely Uniswap V3. Regarding Centralization, even though these two networks are now centralized, but, it would be better to choose Ethereum.
That is true, but that is a question mark on tron and why it's not used more? Like if we are moving TRX and USDT via tron because it's so cheap, even free, then why aren't we using more stuff? I always imagined if you could have tron network used for ALL coins we know, via exchanges mainly, then shouldn't that be a lot better? Move eth, bnb, ltc, avax, sol, whatever you want, all via tron because it's so cheap.
Unfortunately, people somehow don't do it, even bitcoin itself with a bridge would be so perfect, because the cost of bitcoin transactions are still not that low, it could get lower. I personally believe tron is not used as much as it could be and that's because lack of marketing.
