both look better where one's need requires that network.
I will explain why the Binance Smart Chain and the Ethereum network are good in the eyes of their respective users.
Ethereum: Has the advantage of having high community and investor trust, quality published projects with a lack of transactions that are sometimes expensive or unstable.
Binance Smart Chain: The advantage of this Network is that the transaction fees are cheap and stable, only the projects published from this project are mostly not of high quality, but have the same large community as ethereum.
How you are comfortable using it will get better.
