First thing first, it shouldn't be big deal whether which among the two are better. They serve their own purpose on crypto market, they are design with different and unique purpose. But to answer the question, I think eth have the advantage when it comes to nodes. Nodes of eth are much more compare to bsc
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.
