It's about taste, I prefer ETH because it has advantages in terms of technology. The technology offered by the Ethereum ecosystem includes programming languages and platforms for making smart contracts and decentralized applications, which is certainly very effective for developers so it is not difficult to build a foundation for their applications. Whereas BNB is unique in its local function on the Binance exchange, with guaranteed lower trading costs, and when there is a popular IEO with certain conditions involving BNB, the rest is not interesting enough. Actually both of them provide equally good opportunities, our job is to determine the right timing.
It is definitely about taste! Some people simply cannot accept a token that is totally controlled by one company. For me,,, that is what BNB is and nothing more. It is not a crypto, it is not a utility (unless you consider discount tokens as utility because that is all that BNB is!).
I do not see how anyone can seriously compare BNB to ETH!
