For me, ETH will always be better than BSC. Due to the low gas in ETH I recently started using ETH even more often than BSC. There are no innovative projects in BSC so I don't think I will be here for a very long time.
I haven't heard that ethereum has low gas costs, can you show us that ethereum gas costs are cheap, but when it comes to innovative projects, ethereum has it, whereas in BSC only some projects have it, only transaction fees in BNB is still in the cheap category at this time, therefore both have different audiences, depending on the needs that people want.
Yes, BSC is very cheap and ETH is the most expensive, that's why BSC is widely used in projects such as Metaverse and NFT which are used for processing transactions. even though the ETH audience is already very large and is the first smart contract to help developers process transactions on the blockchain. but that's competition, there will be advantages and disadvantages between BSC and ETH but luckily we are the ones who enjoy it the system update
