ERC20 remains popular because ERC20 was the first smart contract before BEP20, so naturally ERC20 is more popular than BEP20 and I think both are very good, then in my opinion it's not ERC20 or BEP20 that determines if the token is good or not, but the projects you want to invest, because if the project is really good, then it will definitely bring you profit, but my advice is if the project is on the ERC20 and BEP20 network, then you better buy it on BEP20, because the gas fees from BEP20 are much cheaper than ERC20.
