Everyone understands BNB coin has a good chance of outperforming Ethereum, which is why I believe BNB will either rise in tandem with Ethereum's price or even surpass it. With the bsc network and a huge exchange behind it, bnb is a currency with a strong chance of surviving. But I'm not sure because the future is still unknown; it's possible that Binance will be shut down due to regulatory difficulties.
BNB is definitely a good choice but i still prefer to stick with ethereum because i know deeply its potentials and how far it will be in the future. But due to its high gas fee, investors are now doubtful to trust in ethereum and so they end up with other good options like BNB or XRP or ADA. I think all crypto coins have its own potentials to grow. They just differ in time with their own developmental progress and so people see them differently.
