Well, I'm not a huge fan of KuCoin either, although I do use it occasionally for spot trading. When it comes to futures trading, I prefer Binance and other top exchanges because their system is more user-friendly. I'm not sure if this update will improve KuCoin's futures interface, but I'll take a look to see what changes have been made so far.
the thing i don't like with kucoin is their complicated interface indeed, even spot trading requires to transfer balance from funding account to trading account which just seems like unnecessary complexity honestly.
I also prefer binance in this case, they are just far simpler than kucoin, with ku coin too much complexity just feels like wasting time.
but when it comes to future trading honestly I think both is on the same level, basically on par in term of features and so on.
therefore I don't really think much about future from both platform its basically the same but maybe binance looks more simpler as you said.
