IMO, ERC20 has more quality coins, community and users than BEP20. However, due to its very high fee, BEP20 has other advantages that make it almost the same or the same as the current ERC20. If the ERC20 fees were lower, I'm pretty sure people would choose to go with ERC20 and BEP20 wouldn't have the chance it has now to be in the same position, it's just, that's not the reality.
In addition, to determine whether it is good or not, we need to refer to the tokens that we use or invest. currently quite a lot of tokens use these 2 chains as their basis.
Because all the whales are on eth and no one wants to see anything build on BSC. People see that ETH is going to be the future so they put their projects where the users are going to be. We are just waiting it for to scale so we can benefit more of that. And after that, there's no use for BSC and even rug pulls move back to eth.
Basically only tokens in BSC worth using are usdt and busd. Placeholder or wrapped tokens that are bridged to BNB (And perhaps the native coin BNB if you are into that sort of thing)
