For now i think it is a even , even though volume of these two exchanges differs hugely. Binance is good to me due to its Easy UI , security , Biggest volume exchange and more coins listed. Kucoin is good for more easy UI , security , and KCS share distribution. I like kucoin more because of kcs. And to me Binance has lost a little respect as they are listing too many coins now a days. But at the end i think every user should use these two exchanges as they are simply awesome.
