Yes trading fees are much cheaper on Binance typically (0.1%), if you pay using binance coin "BNB" you will get typical fees of just (0.05%)

Ether delta typical fees are (0.3%) + other fees.

Once you get used to the trading screen in Binance it's pretty easy, they also have a referral program, competitions and they support the crypto community by launching new projects / companies.

All in all they are tip top & they haven't had any big hacking issues like ether delta has.
