Never did like Etherdelta due to their horrible user interface, laggy website etc. I recommend Kucoin which is far more accessible and sports a much better interface to interact with. I place orders regularly on Kucoin these days and have never been disappointed and am expecting it to grow as big as Binance and Bittrex sometime in the future. Forkdelta is another great exchange which I highly recommend.
Unfortunately the exchanges (KuCoin, Binance, Bittrex) are all centralized exchanges. Im only looking for decentralized exchanges, because I prefer not loosing control over my funds and giving them into custody to a third party. However as for centralized exchanges Im also using KuCoin and Binance and both have not disappointed me so far. They are doing their stuff in a professional manner, unlike many other centralized exchanges.
However I prefer using DEX's and to go a step further Im looking forward to decentralized exchanges that or using Atomic Swaps. With this technology there wont be any custody of traders funds anymore. I believe that the technology will find its way throughout 2018.
