Eth of course. Not only because it has more developers developing in it, but also because it is more decentralized than trx. The nature of trx is DPOS or Delegated Proof of Stake. It is not that decentralized because only a number of nodes control the majority of the mining power of the system. therefore their voting power as well. Think of it as cartel. so if you are just a small node in the network, goodluck to you because you have no voice. It is set to fail. Just like Steem. Steem is a good project. It is a decentralized social media. However, because it's consensus mechanism is DPOS, when Justin Sun bought more than 51% of the node of Steem, he dumped it so hard that the price plummeted and never recovered until now... So that's the danger of DPOS consensus mechanism. It is not that decentralized. We need decentralized system to avoid the 51% attack.
