Binance all the way for me. I just checked coinmarketcap and Binance is on the top of the list as far as 24 hours trading volume:

1. Binance
33. Kucoin

So that speaks a lot. And Binance proves already why they are the number 1 trading platform. Remember the bot exploits? They have a security system built in to check for unnatural movements that's why they have captured the supposedly exploits early and stop the withdrawal and make proper investigations. Resulting of the funds not able to be withdrew by the hackers and they themselves even lost their money. If you are just basing everything on UI alone, then its not a good gauge in my opinion.
