BNB has its own charm but i do agree with your point as binance is run like a private corporate company while eth is a truly decentralized blockchain ecosystem who has global developers working on it so my choice will obviously be ETH too.
both are quite good and we know that BNB has a well-known exchanger of its own, to be able to regulate its trade flow and indeed with the support that is done, it will certainly make BNB very profitable. but we know that ethereum is already known as a reference for all new altcoins that will grow and is well known and recognized and always consistent, so that many investors are still eyeing and making lucrative investments. For development, ethereum is still very popular with investors and has not been replaced by any altcoin to date.
