I would have the same choice too which I do prefer decentralized exchange Ex. Etherdelta. I do really love the site when it comes on trading Erc20 tokens since you can trade it up without the need on giving informations and doesn't have any restrictions or limitations since theres no 3rd party involved which would dictate or require such thing.This is really the biggest advantage compared into a centralized one.The thing I do have on trading on ED is that their graphics is too heavy for it to load for too long and sometimes transactions are too delay even you do put sufficient or high gas but well it does depend on network congestion.
