This is are great exchanges and for me, it's a bit hard to say which I like better cus I clearly like them both, I've used binance alot of times but I think I've used kucoin much more due to the fact they have more coins listed than binance, one area which I must say that binance beat kucoin for me is that binance supports peer to peer trading in my country and also have my local currency list on the platform, but aside this, I would have choosed kucoin cus of their diversity.
