I myself prefer BNB because it is interesting because the Binance network has a smart contract feature with cheaper and faster fees on the network. if ETH is indeed a long-term prospect, this ETH has many benefits, it still has interesting and good potential. Moreover, if system and network updates can be carried out, it will make ETH more effective.
This is more we want to see from which side first, I think both have advantages and disadvantages of each, depending on what our needs are.
You are in this forum since June 28, 2017, which is at this time the Ethereum network is very popular and is used by many new project developers with long-term goals and if you look at when Ethereum was born and had smart contracts, then for now it is very It's worth saying that the Ethereum network is already super long term and even very early in comparison to the Binance network which used to be BNB itself which was also born out of Ethereum smart contracts in the past.
Have you forgotten this now? And don't you remember that in the past only Ethereum smart contracts were the most widely used and went viral in the crypto space?
Try to restore your memories first if you really forgot about this

I'm not saying ETH isn't popular and it's not good, it's actually very good ETH and has great potential from the beginning and I'm also not saying ETH doesn't have a smart contract. I mean the update here is ETH in the process of upgrading to ETH 2.0. We are talking about BNB which is superior because of its low fees and fast transactions. maybe it's a matter of our taste and needs.
