In terms of development and market, I think Binance is more suitable. Cardano is not bad but the use of market-developed technology and platform from binance is more supportive.
binance could become a giant on par with ethereum in the future.
Binance still has a chance to beat cardano and others in the future, because in terms of potential and support and some other excellent features, Binance is dominant in this and can definitely beat the others, but if it's to beat Ethereum, I think it could be more the weight of beating the others.
