I don't think ETH is better than BSC because i have to pay too high gas fee when using ETH network. Because of this high gas fee, i have left Uniswap and some Dapps built on ETH network. I move to BSC and i really love the tech here, gas fee and waiting time make me feel like BSC better than 10 times ETH.
ETH has fixed the biggest problem of user complaints, ETH gas fees have dropped dramatically at the moment and you can see that the current average gwei is only 18 or $0.79 and only $8 for the average trade fee at uniswap. I prefer a project based on ETH network over bsc because I hate rugpull.
