There is no such thing as a better DEX on EOSIO.
BitShares has an order matching engine built-in core - pure P2P
With BitShares you can borrow USD, CNY at 0% APR, rest of the world has interest, up to +20%
BitShares has a Liquidity Pool built into the core, there is no risk of exit-scam by the people who wrote the smart-contract.
BitShares has a shorter LIB than EOSio (except BOSCore)
In the end, I am not bothered by the increases on TLOS, I have quite a lot of these tokens myself :P
