Ethereum is better but BSC seem to be the right choice for developers because of gas fee, the only thing that BSC do better is almost free gas transaction fee, if Ethereum Merge happens by August of this year many developers will go back to Ethereum for future builds.
Now in general there is a very large network of good coins with varying transaction fees, so the cheapness of transaction fees is a particular consideration for everyone, but that I think is more of a necessity because Ethereum is still very good though the gas cost is higher than other networks such as BSC.
So it's not always a bad rating that deserves to be seen from the issue of gas costs alone on a network.
