The best exchange website to trade ERC20 tokens for me is at Idex.market.
I already try etherdelta, etherfork and others but I cannot feel good in that site.
After I tried Idex.market, I found that it's easier for me to send the tokens from MEW wallet into that exchanges.
But sometimes, not all of the tokens are listed on the IDEX, and some of the tokens are list on previous exchanges I mention so you need to check on CMC if the token was release on that site.
for me, i think idex is a good exchange but the one thing that i don't like in that exchange because of the minimum order they have.
but if you trading with a lot of balance maybe you can do it on idex
Oh, so you see in idex have the minimum order?
I don't think that it will be a problem, as long as you can trade with a minimum balance.
So far, I can trade using my balance only in idex, and I don't see the minimum order or maybe I don't aware of that.
