I am not sure if this is a coincidence or indeed ERC is the pioneer, bsc and other platforms started using their POS or dex after seeing the success of ERC20, but they are superior because the fees of other platforms besides erc20 are not that high.
TRX has more fees, but they have some things you can do.
Anyone new to TRON, it is like ETH except that ETH lets anyone mine. TRON is like STEEM where people are elected to mine, like Bitshares and OpenLedger.
So because of the Election situation, there are no "Miners" perse, but instead Super Repreaentatives (SR) who use very littleelectricity, and therefore use very little effort, to mine all the new TRX. So they are almost, so basically, getting it for free in large amounts.
So this then becomes part of an incentive structure, and you vote to earn. Then there are things like the TRON Europe Reward Tokens, which were to pay Europeans to start voting.
They then now built a TRX framework into Steemit because Justin Sun has a large share of the TRX.
So ETH is cheaper, yes. But if you use all of this, then start Cloning contracts into TRX, you can benefit from it as well in a significant way. As TRX is building a Framework, like how Sun was held as a Stake Mining Coin, and then you have coins you hold to mine other coins.
So entering ETH you see more of a side that is more Gambling filled and kinda like a Stock field, while entering TRX you see more of a Gamification of the Blockchain. Anyone can make a TRC10, anyone can clone ERC20 to TRC20, etc. Then everyone focuses on ROI, which gets spammy when you enter 110% a week, or 20% per day, etc. All ROI Tokens should say "you could lose money" and some that are games shouldn't be advertising as money makers, but games. But other than that, there are some good Tokens teaching people how Staking and everything works.
