Both are good coins, having good fundamental too, but you can the negative and positive sides of them, but if that's me, I'll choose bsc/bnb.
Eth has higher price but higher trx fee too, and more holders
Bsc has a little price and lower price, some products, features, and anything has been developed by the ceo
For now, I think more people will choose BSC because in addition to the cheaper transaction fees, the price of the main BSC coin is still very affordable, namely BNB, so anyone can still buy it in several on any exchange.
