Ethereum is a more familiar and popular platform. Of course, it has its drawbacks, but it provides great opportunities for creating coins. It seems to me that it will continue to be popular.
I agree with you that Ethereum will always be popular because ETH does not need to doubt its quality so people will continue to support it, especially ETH is a very good coin for long-term investment so people will not easily sell it cheaply.
so in my opinion the potential of the BNB to beat ETH is very small.
