ERC20 tokens project are most successful than Bep-20 despite of high fee. Possible reason maybe sustainability, security and also that Ethereum is first Blockchain having great network than bsc chain. After successful launch if bsc network, most of big project Erc20 projects issues to their tokens on bsc chain also.

I found many scam and failed project in bsc chain due to easily creation of contract. ERC20 chains tokens are less then bsc but very less failed. The only issue with Ethereum chain is high gas fee and sometimes we have to pay more than 10$ for one transaction especially when we swap through uniswap or other dex.
