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, ETH because of the many benefits it provides, it still has interesting 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.
