https://forkdelta.github.io/Exchange fork etherdelta, they have one smart contract. The exchange is similar to a drain pit. Many of those coins that have not yet entered the normal exchanges are traded, usually not large volumes. The price is often much lower than the ICO. I prefer to use this exchange only as a last resort, it is better to wait for the coin to exit to a normal exchange and sell at a higher price.
Pros:
- low commissions
- verification is not needed for withdraw
- a lot of tokens
Minuses:
- no intuitive interface
- sometimes slows down
Conclusion: I recommend in cases when you need to merge a coin into which you do not believe or buy cheaply the one in which you are sure.

https://idex.market/One of my favorite exchanges. Good volumes. I would recommend that novices take a closer look at it. Of course, not without flaws.
Pros:
- low commissions
- verification is not needed for output
- a lot of tokens
- good volumes
- a fairly clear interface
Minuses:
- laggy, sometimes strongly
- sometimes you have to wait for transactions
- the minimum amount for an order 0.15 ETH (keep in mind at small volumes)
Conclusion: I recommend for constant trading
For me forkdelta is like a place to buy and sell below the price of most the market price, and the fees is above the average, because however, the deposit and withdrawal fees following the recommend Gas & Gwei Price
And idex is very not recommended for constant trading, as you just said the minuses, its high laggy really disturbing
