Which is better BNB or ETH?

I'm curious about the differences between BNB and ETH, could you help me understand which one is better? I've heard a lot about both of them in the cryptocurrency world, but I'm still not quite sure which one to invest in. ETH seems to have a lot of potential with its smart contract capabilities, while BNB seems to be gaining popularity as a utility token. Could you elaborate on their respective advantages and disadvantages, and give me a clear perspective on which one is the better option for the future? Your expertise in the field would be greatly appreciated!
