ethereum is still the best in my opinion because ethereum is a strong platform and is able to increase its quality both in price and volume across the crypto market. Although currently the transaction fees are more expensive than Binance Smart Chains, ethereum prices will continue to increase in the future and I am sure that someday ethereum transaction fees will recover.
Although Ethereum has increased in gas fees, the same thing is happening with BnB, they're also increasing in fees.
But in many terms, it is still Eth that gets the lead. As a counterpart of the high gas fees, it is not odd to see those while the price is at high.
Hopefully, fees for both chains will decrease over time.
