Investors will never look into that and find who is better and who's not. What most important is that we are safely investing the right coin and could benefit in the future.
But for me, ETH has been proven for a very long-time, while BSC is a new project. Maybe we could expect BSC for great help and impact to the market but not that much as ETH's capabilities. It is still a long way to go before BSC was able to compete against ETH.
But Smart chain is just another one of those networks that are built/tweaked to work side by side on ethereum platform with less fees. So there is mo comparison to even begin with in the first place except we are talk talking from a pricing and investment perspective of both two networks. ETH network is currently expensive to use but I know this would be a thing of the past once ETH 2.0 comes online with full swing. Both networks shouldn't be compared even though BSC was created to fill in for some of ETH biggest issues.
